Abstract
PURPOSE:To multipole-magnetize a magnet having the coercive force of 3kOe or above whose multipole magnetization has not been possible, by a method wherein magnetizing yokes are set on both inside and outside of a cylindrical rare-earth cobalt magnet. CONSTITUTION:A 24-pole magnetizing operation is conducted on a cylindrical magnet 3 of phi18.5Xphi16.5mu2mm using inner and outer circumference magnetization yokes 1 and 5. Through iHe=7kOe, BH<CD and a complete magnetization can be conducted, the surface magnetic flux at B point being 1500 gausses. When the cylindrical magnet made of the magnetic powder having different iHc is magnetized on the inner and the outer circumferences, the iHc becomes to 3 kOe or more, and the magnet becomes efficient remarkably.
