Description

[Detailed Description of the Invention] This invention relates to a magnetic field structure of the same magnetic poles having substantially the same magnetic force over the entire area of the same plane with a certain width.

When trying to create a magnetic field with the same magnetic pole on a plane with a certain width, it is necessary to magnetize the same magnetic pole over the entire plane, or to form multiple magnets into a plane with the same magnetic poles at the top and bottom. It is conceivable to place them side by side, but the magnetic field constructed in this way has a phenomenon in which the magnetic force becomes weaker towards the center of the plane, so the magnetic force is the same over the entire plane of a certain size. It is considered extremely difficult to create a magnetic field with the same magnetic poles.

However, if it is possible to create a magnetic field with the same magnetic poles and the same magnetic force over the entire area on a plane of a certain size, by providing a magnetic pole with the same polarity as the magnetic field at the bottom of the object, it is possible to spread the object over the entire area on the plane. It becomes possible to levitate due to the repulsive effect of magnetic force. As a result, it can be used in a wide range of applications, from small toys to large objects.

Therefore, the inventor conducted repeated research experiments to see if it would be possible to create a magnetic field with the same magnetic poles and the same magnetic force over the entire area of a plane of a certain size.
We have developed a magnetic field with the same magnetic poles that has almost the same magnetic force over the entire plane.

As mentioned above, this invention provides a magnetic field structure with the same magnetic poles having the same magnetic force over the entire area on the same plane with a certain width. A magnetic body is formed by magnetizing one pole from the middle to the top and the other pole at the bottom, leaving a non-magnetized part in the entire vertical direction on one side of the magnetic material in the longitudinal direction. The magnet bodies are arranged in a substantially spiral shape on a flat surface with the upper pole facing upward, or a plurality of magnet bodies are arranged with the upper pole facing upward.
They are placed side by side with the poles facing up.

An embodiment of this invention will be described below in detail with reference to the drawings.

In the drawings, reference numeral 1 denotes a magnetic material having a substantially square or rectangular cross section. This magnetic material 1 uses anisotropic ferrite, rubber or plastic containing anisotropic ferrite. A non-magnetized portion 2 is left in the entire vertical direction on one longitudinal side of the magnetic material 1, and one pole 3 (S pole or N pole) is placed from the middle to the top, and the other pole 4 (N pole or S pole) is placed at the bottom. is magnetized to form the magnet body 5.

A magnetic field 6 is formed by winding or juxtaposing the magnet bodies 5 magnetized in this manner on the same plane with one upper pole 3 facing upward. Fig. 3 shows a magnetic field 6 in which magnets 5 are arranged in a substantially spiral shape on the same plane, and Fig. 4 shows a plurality of magnets 5 arranged on the same plane with the upper pole 3 facing upward. The juxtaposed magnetic fields 6 are shown. When a plurality of magnet bodies 5 are arranged side by side, they are installed so that the non-magnetized surface of the adjacent magnet body 5 faces the magnetized surface of one magnet body 5. When the magnet body 5 is provided in a substantially spiral shape, the magnet body 5 may be formed by being wound closely, or may be formed by being wound at appropriate intervals. Further, even when a plurality of magnet bodies 5 are arranged side by side, the adjacent magnet bodies 5, 5 may be placed side by side in contact with each other, or may be placed side by side with an appropriate interval.

The magnetic field 6 thus formed on a plane with a certain width extends over almost the entire area with a slightly stronger magnetic force on the outer periphery, and a magnetic field 6 of the same magnetic poles with almost the same magnetic force is formed. By providing a magnetic pole having the same polarity as the magnetic field 6 applied to the bottom of the object, the object can be levitated over the entire plane surface by the repulsion of magnetic force.

As described above, according to this invention, a long magnetic material with a substantially square or rectangular cross section is made from a non-magnetized part from the middle to the top, leaving a non-magnetized part in the entire vertical direction on one side in the longitudinal direction of the magnetic material. A magnet body is formed by magnetizing one pole at the bottom and the other pole, and the magnet bodies are arranged in a substantially spiral shape on the same plane with the upper pole facing upward, or a plurality of magnet bodies are formed. This relates to a magnetic field structure in which the magnetic fields are placed side by side with the top pole facing upward. By providing magnetic poles with the same polarity as the magnetic field applied to the bottom of the object, it is possible to apply magnetic force to the object over the entire area on the same plane. When moving an object levitated on a flat surface,
Since there is no frictional resistance with a flat surface, objects can be moved with a small amount of force. Therefore, it can be used in a wide range of applications, from small toys to large objects, and is extremely convenient as a magnetic field structure.
Furthermore, since the structure is simple, it is easy to manufacture.
