Description

Industrial application fields

  The present invention is a magnetic brick (Japanese Patent Application No. Hei 6-51334) or clay magnet (Japanese Patent Application No. Hei 7-) that can be manufactured without using a machine when learning a magnet at an educational site such as an elementary school, a junior high school, a high school and a university. The present invention relates to a convenient and simple magnetizing apparatus having a high-performance magnetizing capability that can easily magnetize a non-magnetized material such as 205258) in the width direction instantly and easily.

  Conventionally, the magnetizing device used when learning magnets at educational sites such as elementary school, junior high school, high school, university, etc. uses a magnetizing coil, and the strength of the generated magnetic field is simple magnetization with a magnetizing ability of about several hundred gauss at most. The device is known. This magnetizing device cannot magnetize a non-magnetized material such as a magnetic brick (Japanese Patent Application No. 6-51334) or a clay magnet (Japanese Patent Application No. 7-205258). Therefore, with a simple magnetizing device, a magnetic force of 200 gauss or more is required. It has been considered impossible to manufacture permanent magnets with

  Also, if a non-magnetized material is sandwiched between a pair of permanent magnets with a strong permanent magnet having a magnetic force of about 5000 Gauss, or if a non-magnetized material is sandwiched between a pair of permanent magnets, Magnetization methods to be magnetized are conventionally known. However, one or two or more powerful magnets have a strong attractive force and cannot be separated with bare hands when attached to a magnetizable material, and this magnetization method is impossible. Has been considered.

The problem the device is trying to solve

  As described above, the simple magnetizing apparatus is convenient in the form of a magnetizing coil, but has only a magnetizing ability of about several hundred gauss, and is a magnetic brick (Japanese Patent Application No. 6-51334) or a clay magnet (Japanese Patent Application No. 7-205258). As described above, it is impossible to magnetize a non-magnetized material such as) with several permanent magnets having a strong magnetic force. Therefore, it is an object of the present invention to provide a convenient and simple magnetizing device that is safe and has a strong magnetizing force when learning a magnet at an educational site such as an elementary school, a junior high school, a high school, and a university.

Means for solving the problem

In order to achieve the above object, a convenient and simple magnetizing apparatus of the present invention has a structure having a base made of magnetizable steel that can move in parallel with a predetermined interval when a rotating shaft is rotated. The permanent magnet provided in the base is provided with only one or both of the pair of bases of the vise, and a non-magnetized material magnetized by being sandwiched between the gaps is magnetized in the width direction. It can be made.

Action

  According to such a convenient and simple magnetizing apparatus, a magnetic field of 8000 Gauss to 10,000 Gauss is generated between permanent magnets provided in a vise base having a structure that can move in parallel with a predetermined interval. Magnetization occurs when a non-magnetized material is sandwiched between magnetic fields. Although the attractive force between the permanent magnets provided in the base is very strong, the base can be moved in parallel by the rotating shaft moving structure of vise. Further, when approaching a certain limit value or more, the permanent magnets are joined together, and this limit value becomes the length of the stopper in order to prevent this.

This will be described with reference to FIG. The convenient and simple magnetizing apparatus of the present invention is made of a vise 5 magnetizable steel with a base having a base that can move in parallel with a predetermined interval by rotation of a rotating shaft 1 that can rotate with a weak force. When the permanent magnet 2 arranged in an arbitrary shape is provided on the base 3 with the magnetic force of the permanent magnet, there is no magnetic brick (Japanese Patent Application No. 6-51334) or clay magnet (Japanese Patent Application No. 7-205258) in the gap. When the magnetized material 6 is sandwiched, the magnet is magnetized in the width direction to become a permanent magnet, but is fixed to the magnetized magnet with a strong adhesive force. In contrast, the machining magnet can be separated by rotating the rotary shaft 1 with a weak force. That is, in FIG. 1 (a), when the rotary shaft 1 is rotated, a neodymium system is formed on a base 3 made of magnetizable steel of a vise 5 having a structure that can move in parallel with a predetermined interval. A strong permanent magnet 2 having a magnetic force of about 5000 gauss such as a magnet is provided in the base 3 with the magnetic force of the permanent magnet.

  When the rotating shaft 1 of FIG. 1A is rotated and the interval between the strong permanent magnets 2 provided in the base 3 is narrowed and brought closer than a predetermined interval, the force attracted by the permanent magnets is changed to the permanent magnet base 3. There is a limit value exceeding the adhering magnetic force. A stopper 4 is installed as shown in FIG. 1B so that the permanent magnets do not approach each other beyond this limit value.

  The arrangement of the strong permanent magnet 2 provided in the base 3 will be described with reference to FIG. By combining one or several, it is possible to arrange the N-pole and S-pole arrangement on the base surface in a shape formed by combining arbitrary shapes such as a triangle, a square, and a circle. However, the arrangement of the permanent magnets 2 provided on the pair of left and right bases 3 need not be symmetrical. Further, the permanent magnet 2 provided may be only one of the pair of caps.

  When a non-magnetized material such as a magnetic brick (Japanese Patent Application No. 6-51334) or a clay magnet (Japanese Patent Application No. 7-205258) is sandwiched between the strong permanent magnets 2 provided in the base 3 of FIG. The magnetic pole is opposite to the magnetic pole of the permanent magnet provided in the base, but can be magnetized in the width direction in the shape of FIG.

  The limit value of the distance between the strong permanent magnets 2 provided in the base 3 in FIG. 1B is 2 to 3 millimeters when the permanent magnet provided in the base is a neodymium magnet of about 5000 gauss. Further, when a non-magnetized material such as a magnetic brick (Japanese Patent Application No. 6-51334) or a clay magnet (Japanese Patent Application No. 7-205258) having a thickness of 2 to 3 millimeters with a 95% magnetic powder content is sandwiched in this gap, 300 A permanent magnet of about 400 gauss is manufactured from gauss.

Effect of device

  As described above, the convenient and simple magnetizing apparatus of the present invention has a magnetizing ability that is sandwiched in the gap by a plurality of permanent magnets in an arbitrary arrangement provided in a vise steel base that can move in parallel. A non-magnetized material is magnetized instantaneously and has a constant thickness, but a permanent magnet having an arbitrary shape and an arbitrary magnetic pole can be manufactured.

  The magnetic brick (Japanese Patent Application No. 6-51334) or the clay magnet (Japanese Patent Application No. 7-205258) made by the present invention has a surface of a permanent magnet of 15 mm × 30 mm and a thickness of 3 mm. It was possible to magnetize the pole and the N pole. In addition, the magnetic force retained 300 gauss residual magnetism. This magnet can be used as an unprecedented new teaching material.
