MAGNET MAGNETIZING DEVICE

摘要

PURPOSE:To provide an excellent magnetizing device which can stably and efficiently magnetize even a thin magnetic material or ferromagnetic material. CONSTITUTION:In a magnet magnetizing device which magnetizes a magnetic material 4 by putting the material 4 between a magnetizing yoke 1 and auxiliary yoke 5 counterposed to the yoke 1, the auxiliary yoke 5 is constituted of a nonmagnetic material and wound with a yoke wire 7 and an electric current is made to flow to the yoke wire 7 in the same direction as that of the current flowing to the yoke wire 2 of the magnetizing yoke 1 so that the auxiliary yoke 5 can be easily removed from the magnetized magnetic material after magnetization and the magnetic material can be efficiently magnetized similarly to the case where an auxiliary magnet constituted of a soft magnetic material is used.
