大きな概念を教え込むには問題があつた。 However, with this conventional learning method, students are taught things like, ``There are several types of magnets, such as rod-shaped and U-shaped, and their properties differ depending on the shape.'' Some children create illusions, and U
Have all the children understand that shaped magnets and bar magnets are not separate things, that a U-shaped magnet is made by bending a bar magnet, and that a compass is also the same magnet. Furthermore, there was a problem in instilling the big concept of ``magnets.''
[技術的課題]
本考案は、このような『学習に用いられる教材

Next, a shape retaining means 2 is attached to the rod-shaped rubber magnet to maintain the overall shape in a U shape, and an experiment regarding the U-shaped magnet is performed.
Further, if the magnet is rod-shaped, only the center point thereof is supported, and if it is U-shaped, only the apex of the inverted U-shape is supported, leaving both poles free. As a result, the rubber magnet 1 also functions as a compass, allowing experiments regarding compass needles to be carried out.

Similarly, regardless of its shape, the rubber magnet 1 supports only the center point, and when both poles are freely opened, it also functions as a compass needle.
It is easy to understand that the compass needle, which is usually composed of a thin plate in the shape of an elongated rhombus, is also a magnet.

[実施例]
以下、本考案の実施例を第1図から第7図に基

を設けてある。 The first embodiment shown in FIGS. 1 to 4 uses a bendable metal fitting 2 as a shape retaining means for a bar-shaped rubber magnet 1, and the metal fitting 2 is as shown in FIG. The width of the rubber magnet 1 is approximately the same as that of the rod-shaped rubber magnet 1, and the length is set to be shorter than that of the rod-shaped rubber magnet 1. The bent pieces 21, 21 are made to protrude left and right, and a small recess 22 is formed in the center of the metal fitting 2.

3図のようなU形磁石となる。 To bend a rod-shaped rubber magnet into a U shape, the metal fitting 2 and the rod-shaped rubber magnet 1 are overlapped near the center of the rod-shaped rubber magnet 1, as shown in FIG. Then, attach the metal fitting 2 to the rod-shaped rubber magnet 1. And the metal fitting 2
When the rod-shaped rubber magnet 1 is bent so that the inner surface of the U-shape is bent, the metal fitting 2 is also bent. Due to the rigidity of the metal fitting 2, the rod-shaped rubber magnet 1 resists its elastic restoring force and is bent. It remains as it is, forming a U-shaped magnet as shown in Figure 3.

It turns out.
尚、この実施例で使用した金具2はアルミニユ
ーム等の非磁性体のものが望ましい。 The metal fitting 2 used in this embodiment is preferably made of a non-magnetic material such as aluminum.

せることができる。 In the second embodiment shown in FIG. 5, the non-magnetic thin metal fitting 2 used in the first embodiment is used as a shape retention means, and a double-sided adhesive tape 24 is attached to one side of the metal fitting 2.
, and a protrusion 23 was formed by partially cutting and raising the other side so that a hole for threading passes through it. In this case, the metal fitting 2 is attached to a rod-shaped rubber magnet 1 using double-sided adhesive tape 24.
The bar magnet becomes a U-shaped magnet by simply bending the bar-shaped rubber magnet 1 into a U-shape so that the projections 23 form the outer surface of the U-shape. Further, in this embodiment, regardless of whether it is rod-shaped or U-shaped, simply by passing a thread through the protrusion 23 and hanging it, it will function as a compass needle. In other words, it can be understood more clearly that the properties of a magnet are unrelated to its shape.

い。 In this embodiment, the cap 3 is attached to the bent part of the rod-shaped rubber magnet 1 which has been forcibly bent into a U-shape in advance.
to maintain the U-shaped state of the rubber magnet 1,
form a shaped magnet. Further, in order to function as a direction magnet, the apex of the inverted U-shaped rubber magnet 1 may be supported by the tip of the rod-shaped body, as in the case of the first embodiment. In this case, since the vicinity of the apex of the rubber magnet 1 is covered by the closed portion of the cap 3, there is no fear that the fulcrum will shift and the rubber magnet 1 will slip off the rod-shaped body.
又、このものでは、ゴム磁石1の屈曲部にキヤ
ツプ3を被冠させるだけであるから、保形手段で
あるキヤツプ3の取り外しに手間取らない。 Further, in this case, since the cap 3 is simply placed on the bent portion of the rubber magnet 1, it does not take much time to remove the cap 3, which is a shape retaining means.

り、方位磁石としても機能させることができる。 In the embodiment shown in FIG. 7, a paper or synthetic resin plate 4 with circular holes in the center and rectangular holes at both ends in the longitudinal direction is used as a shape retaining means. The width between the rectangular holes 41, 41 at both ends is made to match the width of both open ends when the rod-shaped rubber magnet 1 is bent into a U shape, and the size is set according to the cross section of the rubber magnet 1. It matches the shape. That is,
In this embodiment, the rod-shaped rubber magnet 1 is bent into a U-shape and both ends thereof are inserted into rectangular holes provided at both ends of the plate-like body, so that the rod-shaped rubber magnet 1 is shaped into a U-shape. It will be retained. In this state, the circular hole 42 provided in the center of the plate-like body 4
By inserting and supporting a rod-shaped object such as a pencil, it can also function as a compass.
この実施例の保形手段は、1枚の板状体4に孔
