PROBLEM TO BE SOLVED: To provide a magnetization method and magnetization device of a permanent magnet by which a perfect magnetization level intensity is achieved, while a waveform for magnetization such as a sine wave, etc., is controlled. SOLUTION: Protruding parts 16a and recessed parts 16b are provided on the surface of an auxiliary yoke 12 on a permanent magnet side material 11. A magnetization yoke 13 is provided on the side of the permanent magnet material 11 opposite to the side facing the auxiliary yoke 12. As a result of this constitution, The magnetism inducing direction of a whole magnet can be controlled by the positions of the protruding parts 16a and angles between the protruding parts 16a in a circumferential direction, so that an arbitrary waveform such as a sine wave, etc., of a magnetic flux density can be obtained without causing decline in a magnetization intensity. |
