Abstract

PURPOSE:To obtain an uniform magnetic field at a gap by utilizing a manetized yoke which has a smaller yoke head than a radius of a ring magnet and has been prepared to have a nearly equal radial length of the yoke head to a diameter of a ring magnet. CONSTITUTION:Relative arrangement between a ring magnet 10 and a magnetized yoke 11 is taken so that a radisur of a yoke head 11a in a magnetized yoke 11 may be smaller than a radius R of a ring magnet 10 and a radial length of the yoke head 11a may be nearly equal to a diameter of the ring magnet 11. Magnetization is performed after insertion of the magnetized yoke 11 into the inner side of the ring magnet 10.
