Description
Technical Field
The invention relates to the technical field of magnetic force application, in particular to an experimental device based on magnetic force asymmetry and a verification method. The invention can also be called an experimental device and a test method based on the magnetic field intensity asymmetry method.
Background
With the development of economy and the progress of society, energy conservation has become a certain social consensus. Magnets have a magnetic field and are capable of generating an attractive force and a repulsive force, and the force generated by the magnets is widely used as a driving force in various electric devices such as motors and generators. However, the difficulty is that the two ends of the magnetic field are symmetrically conserved without magnetic force difference (magnetic field intensity difference), unlike the electromagnetic field which can control the magnitude of the magnetic force, appear and disappear. The resistance at the two ends makes the magnet-to-magnet interaction difficult. So the magnet cannot be used as a power source. If the force between the magnets can be developed, the energy is necessary to be a new energy source.

Lays a foundation for researching magnetic energy sources.

The method is simple and rapid to operate, the whole process of the magnetic asymmetric experiment can be intuitively and clearly demonstrated, and data is collected to draw a curve graph to provide data information for further research.
Detailed Description
The experiment table consists of the following three parts: see attached figure 1
The upper magnetic group, the lower magnetic group and the trolley are three major parts.
The upper magnetic group consists of an upper left magnetic bridge 1, an upper central main magnetic block 2 and an upper right magnetic bridge 3.
The lower magnetic group consists of a lower left magnetic bridge 4, a lower central main magnetic block 5 and a lower right magnetic bridge 6.
The lower magnetic group is fixed on the trolley 7 to form a whole. The trolley 7 is arranged on the horizontal platform track and is pulled by a pulling rope 8. The pulley 9 supports the traction rope 8.
The upper magnetic group is arranged above the lower magnetic group at a certain vertical distance. The upper magnetic group is semi-fixed and can horizontally move and horizontally rotate by 180 degrees left and right. The lower magnetic group moves horizontally along with the trolley 7.
The upper and lower magnetic groups are composed of common magnets. And are bonded together in a shaped arrangement in a manner. The upper magnetic group consists of an upper left magnetic bridge 1, an upper central main magnetic block 2 and an upper right magnetic bridge 3. An upper left magnetic bridge 1 and an upper right magnetic bridge 3 are arranged on two sides of the upper central main magnetic block 2. The cross section of the upper magnetic group is in a cross shape. The magnetic poles of the upper magnetic group are arranged as a reference with the magnetic poles of the central main magnetic block 2. The two poles of the upper central main magnetic block 2 are arranged on two sides of the vertical center line of the upper central main magnetic block. The magnetic poles of the upper left magnetic bridge 1 and the upper right magnetic bridge 3 are arranged, and the magnetic poles of the upper central main magnetic block 2 are sequentially arranged in an unfolding mode. As the magnetic poles of the upper central main magnetic block 2 are arranged in a left-N-right-S sequence perpendicular to the two sides of the central line, the upper left magnetic bridge 1 and the upper right magnetic bridge 3 are naturally attracted with the upper central main magnetic block 2. The lower magnetic group consists of a lower left magnetic bridge 4, a lower central main magnetic block 5 and a lower right magnetic bridge 6. The lower left magnetic bridge 4 and the lower right magnetic bridge 6 are arranged on two sides of the lower central main magnetic block 5. The cross section of the lower magnetic group is trapezoidal. The magnetic pole arrangement of the lower magnetic group is the reference of the magnetic pole arrangement of the lower central main magnetic block 5. The two poles of the lower central main magnetic block 5 are arranged above and below the horizontal central line of the lower central main magnetic block. The arrangement of the pole faces of the magnetic poles of the lower left magnetic bridge 1 and the lower right magnetic bridge 3 is consistent with the pole face of the magnetic pole of the lower central main magnetic block 5. Such as the above N under S arrangement.
The invention is based on the following steps of detecting the magnetic force difference of an experimental platform: see figure 2
Step 1: the trolley and the lower magnetic assembly on the experimental platform are horizontally placed on the track, and a vertical distance is formed between the trolley and the lower magnetic assembly below the upper magnetic assembly. The two sides are pulled apart by a horizontal distance. The direction of the traction rope is taken as a head, and the head of the trolley faces any one side surface of the upper magnetic group. The other end of the traction rope supports a suspended heavy object through the pulley to pull the trolley to approach the upper magnetic group direction. By continuously adjusting the weight of the heavy object, the distance between the trolley and the upper magnetic group is continuously adjusted, so that the trolley does not move any more, and the heavy object does not descend any more. After the two sides are balanced and static, the whole vertical center line of the trolley is still kept at the outer side of the close surface of the upper magnetic group. The weight was then recorded.
Step 2: the upper magnet pack is rotated horizontally with the other side facing the cart and step 1 is repeated again.
According to step 1, the results obtained in step 2 are 0.155 kg: 0.333 kg. And comparing to obtain a group of magnetic force difference data. The method of operation with the low test weight is defined as the forward mode of operation, i.e., the direction of least resistance entry. And defining the maximum output power of the magnetomotive force by using an operation method with heavy test weight. Because the gravity traction direction is opposite to the direction of the magnetic force acting force, and because the whole vertical center line of the trolley is still outside the upper magnetic group approaching surface. Both sides of the upper magnetic group thus present repulsive forces to the trolley. The magnetic force difference is not realized by one of the upper and lower magnetic groups, and the upper and lower magnetic groups are used together to generate the magnetic force difference.
The invention is based on the experimental platform to detect the magnetic force difference distribution of the trolley under the static state, and comprises the following steps: see figure 3
Step 1: the trolley and the lower magnetic assembly on the experimental platform are horizontally placed on the track, and a vertical distance is formed between the trolley and the lower magnetic assembly below the upper magnetic assembly. And pulled horizontally a distance apart.
Step 2: the push-pull dynamometer and the trolley are fixed on a horizontal plane. The push-pull dynamometer is connected with the end of the trolley traction rope through a hard rod.
And step 3: a ruler is arranged on the experiment platform, and a certain interval is marked as a sampling point, such as 3 cm.
And 4, step 4: the upper magnetic group is pushed to horizontally move according to the sampling point interval and the data of the push-pull dynamometer is recorded, so that the upper magnetic group obtains the magnetic force distribution condition through the whole trolley.
The experiment shows that the resistance of one side is smaller than the middle power from the aspect of magnetic force distribution obtained from data, and the experiment result is very similar to the magnetic force difference experiment result. The resultant force at two sides is equal to the intermediate power, which accords with the conservation of energy.
The dynamic magnetic force difference distribution steps of the test trolley of the experimental platform are as follows: see figure 4
Step 1: the trolley and the lower magnetic assembly on the experimental platform are horizontally placed on the track and below the upper magnetic assembly. Spaced apart a vertical distance in the middle. And placing the upper magnetic group and the trolley in a defined forward mode, and horizontally pulling apart for a certain distance. The upper magnetic group is fixed.
Step 2: the push-pull dynamometer is connected with a hard rod at the traction end of the trolley.
And step 3: the push-pull force meter is set to automatically collect data at time intervals, such as 0.1S.
And 4, step 4: the push-pull dynamometer is pulled by even external force, so that the whole trolley passes below the upper magnetic group, and the dynamic magnetic force distribution condition of the trolley is obtained.
The test shows that the resistance of one side is smaller than the middle power from the aspect of the dynamic magnetic force distribution condition of the trolley obtained from data, and the test result is very similar to the results of a magnetic force difference test and a trolley static test. The resultant force at two sides is equal to the intermediate power, which accords with the conservation of energy.
Brief summary
The magnetic array has the innovation that the magnetic field distribution structure is changed through the magnetic array, the large resistance at two ends is changed into the large power in the middle, and a new way is opened for changing the magnetic force into energy.
