Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a regular cube-shaped magnet.
This relates to a cubic magnet in which two pairs of magnetic poles, two S poles and two N poles, are formed on all six sides.

[Conventional technology]

Conventional magnets of this type can be categorized by the shape of magnetization, such as bar magnets and horseshoe magnets, which have N at one end.
magnets with a S pole on one end, and N poles on one end, such as cube-shaped or button-shaped magnets and rubber magnets.
There are two types of magnets, one with a pole on the other side and one with an S pole on the other side, and are used to attract other magnetic materials or as parts of speakers, electric measuring instruments, memory elements, etc.

[Problem that the invention attempts to solve]

However, in the case of regular cubic magnets, where the upper half is magnetized with the N pole and the lower half with the S pole, as in the conventional example above, it can be used as a teaching tool for developing children's sense of volume, such as building blocks. It is unsuitable for such use.

In other words, in the case of a magnet as shown in FIG. 7, four of the six faces are magnetized with half of the north pole and half of the south pole. Therefore, even if you try to stack them, they will be rejected by one of the surfaces, making it impossible to stack them.

The object of the present invention is to provide a regular cube-shaped magnet that can be stacked no matter which side of the cube faces each other.

[Means for solving problems]

In order to achieve the above object, the present invention is equipped with two pairs of magnetic poles, two north poles and two south poles, on all six faces of a cube, and the same poles are arranged diagonally. be.

〔Example〕

The present invention will be explained in detail below with reference to embodiments shown in FIGS. 1 to 6.

In Figures 1 and below, reference numeral 1 denotes a regular cube magnet, and each side is divided into four parts by a line 3 that divides each side 2 into 1/2 equal parts. Each divided portion is magnetized to either a north pole or a south pole, and the arrangement is such that two pairs of north poles and two south poles are provided so that the same poles are on diagonal lines.

Therefore, when the magnets 1 and 1 are brought close to each other as described above, there is a case where the N pole and the S pole are opposite each other as shown in FIG. There are two cases where the positional relationship is as follows.

In the former case, they stick to each other as they are, but in the latter case, the N poles become each other or the S poles become each other, and both magnets 1, 1 repel each other. However, since the part next to it is an S pole or a N pole, if the opposing surfaces are even slightly shifted, the opposite poles will strongly attract each other, and as a result, the upper magnet on the side to be stacked will be flat. It rotates slightly in the direction of the dotted arrow and is attracted.

Next, regarding how to make the magnet according to the present invention, there are two possible methods.

One method is to magnetize a cube-shaped yoke formed by isotropic molding using a capacitor type magnetizer A. As shown in Figure 3, N magnetized parts C are placed on the upper and lower surfaces of magnetizing tables B and B. , C and S magnetized parts D, D are protruded in four pieces respectively, and a coil E is attached to each of the N magnetized parts C and C in a clockwise direction from the bottom to the top, and S magnetized parts D,
The yoke is wound counterclockwise around D, and the yoke is sandwiched between magnetizing tables B and B as shown in the figure, and magnetized by applying current. In this case, since the yoke is formed by isotropic molding, by magnetizing the upper and lower surfaces, the side surfaces thereof are also magnetized as shown.

The above description has been given of the case where one yoke is magnetized, but it is also possible to magnetize many yokes at the same time. For example, as shown in FIG. A large number of S magnetized parts D, D are protruded in an arrangement as shown in the figure, and the four corners of the yoke are sandwiched between both magnetizing stands B, B in a state spanning the N and S magnetized parts, respectively, and magnetized.

Another method is to use magnetized stickers, in which the magnetizable sheet 4 is magnetized in large numbers as shown in FIG. It is formed by adhering to each surface.

〔effect〕

As mentioned above, the magnet according to the present invention is composed of two pairs of magnetic poles on each face of the cube, and the same poles are arranged diagonally, so when the same poles come close to each other, However, with a slight rotation, the different poles will be in a position where they are facing each other.

Therefore, all the surfaces stick to each other, and when used as teaching tools such as building blocks, they can be arranged and stacked accurately in the vertical, horizontal, and height directions, making it easy to put them into practical use. The effect is significant.
