Description

Utilization of Magnetic field

The present invention relates to a technique for utilizing the force in the magnetic field to which the force (magnetic force) of the magnet acts.

Generally speaking, a magnetic body refers to a magnet that is generated in a solid body. A solid magnetic field is applied to such a material to align the magnetic directions of the individual magnetic bodies in the same direction. It is called.

The magnetic poles of the same polarity repel each other between the two permanent magnets, and the magnetic poles of the opposite polarity act on each other, which is called a magnetic force. The magnetic force acts on the periphery of the magnetic poles The space is called the magnetic field, and the magnetic field affects the electric charge to move. The electric charge to move can generate the magnetic field and express it by the magnetic force line (magnetic force line).

The magnetic field is a vector quantity having magnitude and direction, and its magnitude is expressed by magnetic field H (magnetic field strength) or magnetic field B (magnetic flux density). The magnetic field H is an amount that does not consider the magnetic characteristics of the space in which the magnetic field exists, and the magnetic field B is an amount directly used in calculating the magnetic force in terms of the magnetic characteristics. The magnetic field H and the magnetic field B have a relationship of B = μH. μ is the magnetic permeability, which is the magnetic property of the space in which the magnetic field is placed.

As there are electric charges at both ends of the electric force line, there is a magnetic subdivision in the magnetic force lines, and there exists always the same amount of N pole and S pole, and the magnetic force line defines the direction from the N pole to the S pole as positive direction.

In order to obtain energy from magnetic moments in a magnetic field composed of two or more permanent magnets, a force is continuously generated between the magnets and mutually crossing each other.

When the magnet is perpendicular to the magnetic field, that is, when the magnetic axes of two permanent magnets connecting the N pole and the S pole are located in a straight line, the potential energy is zero, but when the magnet has a constant angle θ, When the magnet and the magnetic field are parallel, that is, when the magnetic axes of two permanent magnets connecting the N pole and the S pole are formed at right angles, the potential energy (static magnetic energy) is maximized. It can rotate.

It aims to promote industrial development by obtaining energy from linear and rotary motions using magnetic fields.

Preferred specific embodiments of the use of the magnetic field according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a hypothetical line of magnetic force in which a pair of N poles and S poles appear at both ends in one permanent magnet, and both ends of the permanent magnet have a strong force on the magnetic body while a central portion has almost no magnetic force.

FIG. 2 shows that the axial direction of the magnetic pole and the magnetic line of force are perpendicular to each other when two identical permanent magnets face each other, and the repulsive force acts between the two magnetic poles in the direction perpendicular to the magnetic line tangent line. FIG. In the case of viewing, the axial direction of the stimulus and the magnetic line of force are parallel, so that the pulling force (attracting force) between the two magnetic poles acts in the direction perpendicular to the magnetic line of force.

2 and 3 are orthodox that the axis of the magnet connecting the N pole and the S pole is located in a straight line, so that no potential energy of the magnetic moment is generated. Refers to the magnetic efficiency of a magnetic body reacting to an external magnetic field.

In other words, the product of the intensity of the magnetic pole and the length is the fundamental physical factor of the magnetic body (i.e., the intrinsic characteristic of the object), which is the most fundamental factor determining the magnitude of the rotation moment with respect to the magnetic field. It is a moment. However, it should be noted here that there is a directional relationship between the internal magnetic field and the magnetic moment. That is,

That is, from the S pole to the N pole, and therefore they are opposite to each other.

If the magnet is inclined with respect to the magnetic field direction, it has a larger potential energy compared to when it is parallel. If the magnet is placed in an arbitrary direction not parallel to the magnetic field in the magnetic field, the position energy is rotated in the direction of lowering the energy.

In the above description, when the magnet is perpendicular to the magnetic field, that is, when the magnetic axes of the two permanent magnets connecting the N pole and the S pole are positioned on a straight line, the charge energy is zero, but when the permanent magnet has a constant angle The potential energy (static magnetic energy) is maximized when the magnet and the magnetic field are parallel, that is, when the two permanent magnets connecting the N and S poles are formed at right angles to each other .

In the permanent magnet of FIG. 5, the strongest magnetic point at each of the N and S poles is called a magnetic pole (SP11, SP12, NP11, NP12), and the magnetic pole is a line connecting the same magnetic pole points in the length direction of the magnet. Is called a magnetic pole line, and the surface which connected the N magnetic pole line and the S magnetic pole line is called a magnetic pole surface.

In Fig. 5, in the three-dimensional space composed of the x, y, and z axes, a movable permanent magnet 10 having a long shape is installed so that the magnetic pole surface of the magnet is parallel to the y axis, and another small shape is fixed. After the permanent magnet 20 is installed so that the magnetic pole surface of the magnet is not parallel to the x-axis (parallel to the y-axis and the z-axis), the movement of the permanent magnets 10 and 20 in the y-axis and z-axis directions is controlled, respectively. If only the x-axis direction is freed, a force that crosses each other in the x-axis direction between the two permanent magnets. At this time, when the upper side of the elongated permanent magnet 10 and the right side of another fixed small permanent magnet 20 are provided with N poles as shown in Fig. 5, the movable permanent magnets 10 ) Is subjected to a force to the left, and another fixed permanent magnet (20) having a small shape receives a force to the right.

Figure 6 is a cross-sectional view of an example of a simple experimental device for confirming the principle described in Figure 5, the upper side of one of the elongate movable permanent magnet 10 to the N pole and the lower side to the S pole to move up and down After being installed between the rollers 11 and 12 that are free to control and move horizontally, another small shape fixed permanent magnet 20 is fixed on the upper side thereof with the fixing devices 21, 22 and 23 to form a long shape. It is found that the movable permanent magnet 10 moves to the left to move, and from this it can be reliably confirmed that the principle of FIG.

In order to attempt to magnetize the permanent magnet, it is generally required to have a magnetization force of at least five times the coercive force of the material. In the case of the present invention, there are various methods such as the inner and outer diameter monopolar magnets 77 and the inner diameter multipolar magnets 79 in the circular ring. It will be described in detail with respect to the case using.

A magnetic axis connecting the fixed permanent magnets 40 to 47 to the north pole of each magnet from the north pole to the south pole of one magnet on a plane with a minute spacing to the permanent magnet 30 of a shape is perpendicular to the permanent magnet 30. If the installation is fixed so as to form a concentric circle at the center of the shaft 50, the inner and outer diameter of the polarized ring shape of the permanent magnet 30 of the permanent magnet 30 is rotated continuously about the center axis do.

As shown in FIG. 8, the outer side of the permanent magnet 30 of the inner and outer diameter monopolar magnets is magnetized to the N pole and the inner side thereof to the S pole, and the individual fixed permanent magnets 40 are mounted on the shaft 50. When viewed from the right side to the N pole to the left to the S pole, the permanent magnet 30 of the circular ring shape is rotated continuously in the counterclockwise direction.
