ABSTRACT:
A polar-anisotropic ring magnet having magnetization directions in alignment with its normal line at each magnetic pole position and in alignment with its tangential line at each middle position between adjacent magnetic poles, and having a substantially constant angle difference in a magnetization direction between adjacent elements, the elements being obtained by division at an equal angle pitch between the magnetic pole position and the middle position adjacent to the magnetic pole position.
