Claims

[Scope of utility model registration request]

A radial direction comprising a plurality of outer cores and an inner core each having a coil, a magnetic material is fitted between the plurality of outer cores and the inner core, and the magnetic material is magnetized by energizing the coil. In the magnetizer, a groove for setting the magnetization angle of the magnetic material is formed in the inner core at a position facing the intermediate portion of the adjacent outer core, or the tip of the outer core is made removable; A radial direction magnetizer characterized in that the shape is narrowed toward the magnetic material.
