Abstract
To provide a magnetizing apparatus and magnetizing method in which, even in preparation of a ring-shaped permanent magnet having a narrow magnetization pitch with multiple poles magnetized on an extremely small diameter, sufficient magnetization and high magnetization quality can be achieved and powerful magnetization can be carried out efficiently and quickly at low cost. A permanent magnet magnetizing apparatus includes a heating section, a magnetizing sectionaxially disposed as a discrete structure from the heating section, and a holding memberfor holding magnetization objectand movable relative to the heating section and the magnetizing section. The magnetization object heated in the heating section is transferred to the magnetizing section and is magnetized therein.
