RADIAL ANISOTROPIC RING MAGNET AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a radial anisotropic ring magnet which has excellent magnetic characteristics and a manufacturing method of the same in which the ring magnet is formed by a horizontal magnetic field vertical forming method. SOLUTION: The magnet is characterized in that the angle formed by the central axis of the ring magnet and the direction of imparting a radial anisotropy is in the range of 80°to 100°over the whole magnet.
