Description
Technical Field
The invention relates to the technical field of magnetizing or demagnetizing equipment or methods, in particular to a method for establishing an extremely weak magnetic field in a target space, magnetizing equipment and a magnetized product.
Background
The magnetic induction is a physical quantity describing the strength and direction of a magnetic field, is a vector, is commonly represented by symbol B, is internationally commonly expressed in units of tesla (symbol T), and is expressed in units of gauss (Gs) in the gaussian system, 1 t=10 4 Gs. Magnetic induction is also known as magnetic flux density or flux density. In physics, the strength of a magnetic field is expressed by the magnetic induction intensity, and the larger the magnetic induction intensity is, the stronger the magnetic induction is, and the smaller the magnetic induction intensity is, the weaker the magnetic induction is. The magnetic field has very important effects on biological and medical research, physiological, production, work and the like of people, and the research finds that when the magnetic field acts on the human body, the nervous system and the endocrine system are most sensitive to the feeling of the magnetic field, and the nervous system which is most sensitive to the magnetic field acts, especially the hypothalamus and cerebral cortex are most prominent. As same asIt was found that the brain of the laboratory rat is significantly damaged in a low-magnetic-field environment, and it is of course not possible to completely avoid such adverse effects. People often receive weak magnetic fields in daily life, and devices for generating the weak magnetic fields are usually located near the brains of people, for example, mobile phones, electric tools commonly used in hairdressing industries, electric blankets commonly used in life, electric shavers and the like, and according to the research results obtained at present, the harm of the weak magnetic fields to the brains is likely to accumulate with the increase of time, so that people cannot feel careless.
In addition, each industry needs objective and accurate EMC assessment of electronic products or devices, EMC is an abbreviation of Electro Magnetic Compatibility, chinese is translated into electromagnetic compatibility, which refers to the ability of a device or system to operate satisfactorily in its electromagnetic environment without intolerable electromagnetic interference to any device in its environment, and thus EMC includes EMI (interference) and EMS (susceptibility), i.e., electromagnetic interference and electromagnetic interference immunity. EMI, electromagnetic interference, describes the degree of electromagnetic radiation interference of a product on other products, whether it affects the normal operation of other electronic or electrical products in its surroundings or in the same electrical environment. EMS, electromagnetic immunity, describes whether an electronic or electrical product will interfere with its surroundings or other electronic or electrical products within the same electrical environment, affecting its proper operation. EMI in turn includes conducted interference CE (conduction emission) and radiated interference RE (radiation emission) and harmonic halonic.
The magnetic induction intensity calculation formula: b=Φ/S, where Φ is the magnetic flux and S is the area perpendicular to the magnetic field direction. The magnetic flux represents the number of lines of magnetic induction passing through a certain area, is a scalar quantity, has positive and negative divisions, and positive and negative do not represent directions, and only represents the penetration or the penetration of the lines of magnetic induction. The magnitude of the magnetic flux passing through a certain plane can be visually described by the number of lines of magnetic induction passing through the plane. The greater the magnetic induction, the denser the induction line in the same magnetic field. Thus, the larger B, the unchanged S, the larger the magnetic flux, meaning the greater the number of lines of magnetic induction across this face. If there are two magnetic fluxes with opposite directions passing through a plane, the resultant magnetic flux is the algebraic sum of the magnetic fluxes with opposite directions (i.e., the magnetic fluxes remaining after the magnetic fluxes with opposite directions cancel).
Based on the theory, the current general magnetic induction intensity testing methods are numerous, and the main stream method mainly comprises 9 methods of a current balance method, a force balance method, a dynamics method, a functional relation method, a magnetometer vector method, an action measurement of a magnetic field on conductive liquid, a measurement based on fiber bragg grating differential group delay, an alternating magnetic induction intensity measurement through a coil, an instant magnetic induction intensity measurement through a Hall effect and the like.
The method has the common characteristic that the method is based on the group effect of the induction lines, belongs to a measurement method under the ideal condition of the induction lines in a single direction, and the measured result is that the vector sum of the induction lines, namely two groups of induction lines with opposite directions and equal quantity, can be mutually offset on the same plane, the final vector sum is the result of subtracting the numbers of the two groups of induction lines, and people obtain the magnetic induction intensity based on the test method so as to judge whether the magnetic field is harmful to human bodies, electronic equipment or production and life.
This measurement method has significant limitations. Firstly, the real space is a complex electromagnetic environment, the directions of magnetic induction lines in the space are different, the directions of the magnetic induction lines in the space are not possible to be the single directions, the ideal environment meeting the ideal conditions cannot exist, when the directions of the magnetic induction lines in the real space are inconsistent, the measurement result obtained by the measurement method taking the single direction as the measurement premise deviates from objective reality seriously, the measured magnetic induction intensity is far smaller than the actual magnetic induction intensity of a magnetic field, namely, missed magnetic induction lines exist, and the missed magnetic induction lines inevitably influence the production, life, scientific research and work of people, therefore, the inaccurate data are applied to guide the production, life, scientific research and work, the directions of biology and medical research are possibly misled, meanwhile, catastrophic results are possibly caused to the health of people, the gene mutation is caused, the cancer risk is increased, and the electronic equipment cannot work normally due to EMI, so that the production, life, scientific research and work of people are brought about great adverse effects. Which is a kind ofThe magnetic induction intensity which can be measured based on the above method has a minimum value (i.e., the measurement accuracy of the measuring apparatus), and the measurement results are uniform in the case where the magnetic field is not present and less than the minimum value, and therefore, for extremely weak magnetic fields such as 10 -5 T ～10 -12 A magnetic field of even weaker magnitude T, when the measurement accuracy of the above measurement method is insufficient, i.e. no magnetic field is indicated, is clearly contrary to the objective fact.
It is clear from this that the limitations in measurement technology and cognition prevent people from objectively recognizing and reasonably utilizing the extremely weak magnetic field, and certainly, the establishment and application of the extremely weak magnetic field also become a technical blank.
It should be emphasized here that the term "extremely weak magnetic field" here refers in particular to a magnetic field which is close to the measurement accuracy of the measuring device used in the above-mentioned measuring method or a magnetic field which cannot be perceived, and the term "weak magnetic field" mentioned above is not an equivalent concept, and refers to a magnetic field which can be measured by the currently known and commonly used measuring method, but only with a smaller measured value.

As is well known, the earth core is a large sphere composed of iron, nickel and other substances, and the temperature is above 5000 ℃. The outer layer of the earth core is composed of liquid metal, and due to the temperature difference between the liquid metal of the outer layer of the earth core and the solid metal of the inner layer, the liquid metal of the outer layer continuously convects to generate a plurality of eddies so as to generate a geomagnetic field, wherein the magnetic induction intensity of the geomagnetic field on the earth surface is about 0.3-0.7 Gs, namely 3-7 multiplied by 10 -5 T. The earth magnetic field protects the life on the earth from attack of high-energy particle flows from the sun and the universe, which can lead to gene mutation, and if the earth magnetic field does not exist, the strong charged particle flow (commonly called solar wind) emitted from the sun is not deflected by the action of the earth magnetic field and is directly irradiated to the earth, and under the bombardment of the high-energy particle flow, the atmospheric components of the earth are probably not the present state and the life cannot exist, so that the earth magnetic field is a top protection umbrella is important for us. When the solar wind comes out of 7 km of the earth, the magnetic induction line of the magnetic field of the earth is encountered, the range extends from 7 km to 700 km from the surface of the earth, the solar wind is controlled by the magnetic induction line of the earth in the range and moves along the magnetic induction line in the process of travelling towards the earth, and then the hydrogen ion wind starts to deviate from the direction of blowing towards the earth or is vertically crashed towards the north and south poles of the earth along the magnetic induction line of the magnetic field.

Detailed Description
As shown in FIG. 1, the method for establishing the target space extremely weak magnetic field comprises the following steps:
s1, selecting materials: according to the specific application requirements of the target space, a certain permanent magnetic material is selected as a raw material, and a plurality of candidate materials of the preferable raw material are: magnetic materials such as martensitic or ferritic stainless steel and materials containing small or minute amounts of magnetic atoms or molecules, such as alloy materials, composite materials, natural materials, or the like. Preferred alloy materials are: an aluminum alloy; preferred composite materials are as follows: ceramics, glass, rubber, plastics; preferred natural materials are: jades, crystals, agates, and the like.
The permanent magnetic material is also called as hard magnetic material, and can keep constant magnetic property after magnetization, and has wide hysteresis loop, high coercive force and high remanence. The commonly used permanent magnetic materials are divided into an alnico permanent magnetic alloy, an iron-chromium-cobalt permanent magnetic alloy, a permanent magnetic ferrite, a rare earth permanent magnetic material and a composite permanent magnetic material. Martensitic or ferritic stainless steels such as 430, 420, 410, 409, etc., are magnetic. Austenitic stainless steels such as SUS304 stainless steel, 321, SUS316 stainless steel, and 310 are nonmagnetic or weakly magnetic. The nonmagnetic austenitic 304 stainless steel is transformed into magnetic martensite by structural transformation formed by cold working, and thus, the 304 stainless steel is magnetic but weak.
The magnetic field strength is an auxiliary physical quantity introduced when researching magnetic media and deducing ampere loop theorem of the magnetic media, has no physical meaning, is a vector, and is expressed as H, and the unit is ampere/meter (A/m). The unit of H in the gaussian system of units is oersted (Oe), 1A/m=4pi×10 -3 Oe，1 Oe=1 Gs=10 -4 T，1 A/m =4π×10 -7 T. After saturation magnetization of the magnetic material, the external magnetic field returns to zeroWhen the magnetic induction B does not return to zero, the magnetic induction B can return to zero only by adding a magnetic field with a certain size in the direction opposite to the original magnetic field, and the magnetic field is called coercive field, which is also called coercive force (coercive force). The coercive force Hc is high, the Curie temperature Tc is high, and the saturation magnetization Ms is high. Coercive force of permanent magnetic material>1000A/m（1000A/m=4π×10 -4 T) coercivity of soft magnetic material<100A/m, and the minimum of 0.08A/m.
The magnetically soft material has low coercivity and is easily demagnetized after being magnetized to saturation and removing the external magnetic field. Steel (carbon content < 2.11%) or other materials can become permanent magnets because the internal non-uniformity is in an optimal state and the coercivity is maximized after proper treatment and processing. The crystal structure, internal stress and other non-uniformity of iron are small, so the coercive force is small and the iron cannot become a permanent magnet.
S2, forming: according to the product shape required by the application scene, the raw materials are processed into a molded product or the selected raw materials are used as main materials or auxiliary materials and other materials (such as a small amount or trace amount of magnetic atoms or molecules are used as auxiliary materials to be added into alloy and composite materials, or silk-type magnetic materials are woven with cotton, chemical fibers and the like) are processed into the molded product through the existing mature process flow, preferably, the molded product can be foil-type, sheet-type, multi-petal annular, strip-type, block-type, silk fabric-type, particle and the like in order to be capable of establishing an extremely weak magnetic field. The present embodiment only lists some common forms, and can be made into various forms as required, which is not exhaustive here.
S3, magnetization: the method comprises the steps of applying an external magnetic field to a molded product to magnetize the molded product to obtain a final product, wherein the magnetic field strength of the external magnetic field is 3-5 times of the coercive force of the raw material, the final product establishes an extremely weak magnetic field in a target space nearby the final product, and the magnetization direction is perpendicular to the flow direction of dipole flow or charged particle flow in the target space to which the product is applied, so that the molded product can generate magnetic induction with the magnetic induction strength of about 10 in the target space to which the product is applied -5 T～10 -12 An extremely weak magnetic field of the order of T.
In particular, the permanent magnet has high magnetic line density, the number of magnetic particles per unit volume of the material is very large and the finished product is thick, but the final molded product of the present application has very low magnetic line density, the number of magnetic particles per unit volume of the molded product is extremely small or the finished product is thin, and thus an extremely weak magnetic field is obtained.
S4, plastic packaging: when the molded product is of a foil type, in order to ensure use safety, the final product of the foil type is sent into a plastic packaging machine, and plastic packaging treatment is carried out by utilizing the existing mature plastic packaging technology, so that plastic packaging is completed, and packaging shipment is realized.

The magnetizing assembly 3 comprises a magnetic conduction column 4, the magnetic conduction column 4 is a C-shaped rectangular frame, a coil A31 is fixedly connected to a top plate 41 extending out of the magnetic conduction column 4 along the horizontal direction, a coil B32 is fixedly connected to a bottom plate 42 extending out of the magnetic conduction column 4 along the horizontal direction, the coil A31 and the coil B32 are symmetrically arranged up and down, a pole head A33 and a pole head B34 are coaxially arranged at the center of the coil A31 and the center of the coil B32 respectively, and the pole head A33 and the pole head B34 are cylindrical and have the same diameter.
The magnetizing assembly 3 is also provided with an adjusting assembly 8, and the pole head A33 and the pole head B34 can move oppositely or separately under the action of the adjusting assembly 8. The adjusting component 8 comprises a shell A81, a shell B82, a threaded rod A83 and a threaded rod B84, wherein the shell A81 and the shell B82 are respectively fixed on the top plate 41 and the bottom plate 42, a threaded hole which does not penetrate through the center of the pole head A33 and the center of the pole head B34 is formed in the center of the pole head A33 and the center of the pole head B34, the two threaded holes are coaxial, one end of the threaded rod A83 and one end of the threaded rod B84 which are in a T shape are in threaded connection with the pole head A33 and the pole head B34 through the threaded holes, and the other end of the threaded rod A83 and the threaded rod B84 are in rotary connection with the shell A81 and the shell B82. Preferably, sealing rings are arranged at the joints of the threaded rod A83 and the shell A81 and the joints of the threaded rod B84 and the shell B82 to prevent magnetic leakage. Pole head a33 and pole head B34 are connected to casing a81 and casing B82 by threaded rod a83 and threaded rod B84, respectively, and move in the respective axial directions when threaded rod a83 and threaded rod B84 rotate. The ends of the threaded rods A83 and B84 extending out of the casings A81 and B82 are fixedly provided with handles 85. Preferably, the handle 85 is arranged in a "eight" shape. Turning the handle 85, the threaded rod A83 or the threaded rod B84 correspondingly drives the pole head A33 or the pole head B34 to move along the respective axial directions, or move towards each other, or move away from each other. The handles 85 on the threaded rods a83, B84 can be rotated simultaneously or individually as desired.
Preferably, a threaded blind hole is formed in the center of one end, close to each other, of each of the pole head A33 and the pole head B34, a threaded protrusion A matched with the threaded blind hole is arranged in the middle of the adjusting block A332, the adjusting block A332 can be mounted on the pole head A33 by installing the threaded protrusion A into the threaded blind hole on the pole head A33, and similarly, the adjusting block B342 has the same structure and usage as the adjusting block A332, and the details are omitted. When the axial distance between the pole head A33 and the pole head B34 is larger, the distance can be reduced by arranging the adjusting block A332 and the adjusting block B342, so that the magnetizing process requirement can be met, and the method is convenient and quick.
Preferably, a limiting groove a331 is formed on the outer wall of the pole head a33, and the limiting groove a331 is located at the upper half part of the pole head a33 and extends along the axial direction of the pole head a 33. Similarly, a limiting groove B341 is also formed on the outer wall of the pole head B34, and the limiting groove B341 is located at the lower half of the pole head B34 and extends axially along the pole head B34. The limit groove A331 and the limit groove B341 do not penetrate through the pole head A33 and the pole head B34 along the axial direction. Screw holes perpendicular to the pole heads A33 and B34 are respectively arranged on the top plate 41 and the bottom plate 42, and the positioning pins A411 and B421 are respectively inserted into the corresponding screw holes from the edges of the top plate 41 and the bottom plate 42 and advance and retreat in the screw holes in a threaded fit manner. Taking the positioning pin A411 as an example, when the positioning pin moves towards the pole head A33, the end part of the positioning pin stretches into the limiting groove A331, so that the axial moving distance of the pole head A33 can be controlled, and the pole head A33 can be effectively prevented from rotating along with the threaded rod A83. The structure and usage of the positioning pin B421 are the same as those of the positioning pin a411, and the description thereof will not be repeated here. Because the width of the limit groove A331 and the limit groove B341 are matched with the diameters of the locating pin A411 and the locating pin B421, the locating pin and the limit groove cooperate to effectively limit the movement of the pole head. More preferably, in order to facilitate the operation of operators, the positioning pins A411 and B421 are fixedly connected with a handle 9, and the two positioning pins can be pushed in or withdrawn by rotating the handle 9.

Preferably, handles 531 are arranged at intervals on the long edges of the two sides of the push-pull plate 53. In this embodiment, handles 531 are respectively arranged at the head and tail of the two long edges, so as to facilitate push-pull operation.
Referring to fig. 8, reference numerals a, B, and c denote tangential directions of a magnetic induction line, and when the magnetization step is performed, the molded product 100 is located at a central position along an axial direction between the pole head a33 and the pole head B34, so as to improve consistency of magnetization directions of various positions inside the molded product. In order to further ensure consistency of magnetization directions throughout the inside of the molded product, when the molded product 100 is in a strip shape or a belt shape, it is pushed from left to right or from right to left, and the diameter of the pole tip a33 or the pole tip B34 is larger than the width of the molded product 100. When the molded product 100 is in the form of a foil disc or a thin disc, the diameter of the pole tip a33 or the pole tip B34 is larger than the width of the molded product 100, but the width refers to the diameter of the finished disc, and other shapes are similar, so that the description is not repeated. As shown in fig. 8, in the region opposite to the pole tip a33 and the pole tip B34, each magnetic induction line vertically passes through the molded product 100 to be magnetized, and if the entire molded product 100 falls into the region, that is, is completely covered by the region, the uniformity of magnetization directions of the molded product is the best. If the molded product 100 has a larger axial dimension along the pole tip (i.e., a larger thickness dimension) and a length greater than the pole tip diameter, the space magnetic induction linear density beyond the pole tip diameter decays very rapidly, resulting in insufficient magnetization of certain portions of the molded product 100. In order to solve the problem, during magnetization, the molded product is firstly placed on the push-pull plate 53 in parallel, namely, the length direction of the molded product is consistent with the length direction of the push-pull plate 53, then the molded product is pushed through the pole head from the conveying section to the receiving section to finish preliminary magnetization, then the molded product is horizontally rotated by 90 degrees to be vertical to the length direction of the push-pull plate 53, the pole head is reversely pushed again to perform secondary magnetization, and the problem of poor magnetization effect of the edge part of the product is thoroughly solved through the secondary magnetization. The finished product may also be segmented magnetized with reference to the second magnetization process.
The above-mentioned method can be used to obtain a magnetized product, and said magnetized product can be used for creating an extremely weak magnetic field in the target space of its application, and its magnetic induction intensity is about 10 -5 T～10 -12 T-magnitude is harmless to human body or related equipment, but when dipole flow (e.g. water dipole flow, i.e. water flow) or charged particle flow flows through a target space where an extremely weak magnetic field has been established, the extremely weak magnetic field of the target space causes turbulence of the dipole flow (e.g. water dipole flow, i.e. water flow) or charged particle flow, so that the aggregation state between microscopic particles of the fluid is changed, thereby changing the physical and chemical properties of the fluid. For example, the extremely weak magnetic field can change the aggregation state of water molecules and other hydrogen-bonded molecules with high efficiency, namely, the state of a macromolecular group is changed into a state of a small molecular group, so that the effective water dipole number is increased, and the water dipole is hydrated with other cations and anions due to electrostatic attraction, so that the physical properties, chemical properties and the like of charged microparticles are changed; meanwhile, the change of the aggregation state of water molecules and other molecules with hydrogen bonds also brings about the change of the self-properties of the water body, such as reduced viscosity, improved fluidity, improved heat conductivity, improved solubility, improved permeability and the like. In a word, through extremely weak magnetic field high-efficient change the condensation state of hydrone and other hydrogen bond molecules, and then changed charged microscopic particle's physical property and chemical property, above-mentioned magnetization product is applied to industrial pipe network and heat exchanger circulating cooling water's processing, can play the anticorrosive effect of scale inhibition. Similarly, the extremely weak magnetic field effectively changes the aggregation state of water molecules, so that the viscosity of blood in a human body is reduced, the fluidity is improved, the solubility is improved, the permeability is good,the magnetized product is applied to cardiovascular and cerebrovascular health care, and can effectively improve the nutrition supply of the cardiovascular and cerebrovascular, relieve fatigue, reduce altitude stress, alleviate dysmenorrhea symptoms and improve immunity. In addition, the magnetic field generated by the magnetized product is an extremely weak magnetic field, so that the permanent damage to people and organisms caused by the induction of gene mutation by a strong electromagnetic field or high-energy particle flow is fundamentally avoided, the method has important guiding significance on the research of biology and medicine, and meanwhile, the health of the people can be effectively maintained.
In addition, the final product obtained by the magnetizing device and the method can be used for establishing an extremely weak magnetic field in a target space, and the magnetic induction intensity of the final product can be known by measuring the residual magnetic induction intensity of the final molded product by using the existing measuring device with ultra-high measurement precision (such as special equipment of a metering institute).
