PURPOSE:To make it possible to open the new fields of utilization of rotary machine and the like, by forming a polyhedron by incorporating a plurality of magnetic blocks so that only one surface of the polyhedron has a different magnetic pole. CONSTITUTION:A polydedron 1 made of a desired magnetic material such as Alnico, ferrite, and the like are formed by incorporating a plurality of magnetic blocks 4-8. One surface of said polyhedron 1 is magnetized as an S pole, and other surfaces 3 are magnetized as an N pole, thereby a permanent magnet M is obtained. The shape of the polyhedron 1 is a fan shaped hexagonal body, which is constituted by an upper magnetic block 4, a lower magnetic block 5, a right-side magnetic block 6, a left-side magnetic block 7, and an outside magnetic block 8. The surfaces of the magnetic blocks 4-8 are magnetized so that one surface 2 is an S pole and the other surfaces 3 are N poles. Therefore, assembling work is performed so that only one surface 2 at the outside of the hexagonal body has the different polarity. Said polyhedron 1 is used in rotary machines and the like and the new fields of utilization are opened. |
