Abstract
A permanent magnet includes two or more separate permanent magnet pieces each having a rectangular parallelepiped shape with a fractured surface formed when a permanent magnet block is fractured. The separate permanent magnet pieces include a first separate permanent magnet piece and a second separate permanent magnet piece. At the time when the permanent magnet block is fractured, the first and second separate permanent magnet pieces are adjacently located and a first fractured surface of the first separate permanent magnet piece and a second fractured surface of the second separate permanent magnet piece are adjacent to each other. The permanent magnet is configured such that the first fractured surface of the first separate permanent magnet piece and the second fractured surface of the second separate permanent magnet piece are located in positions out of contact with each other.
