Abstract

PURPOSE: To obtain a magnet greater in the magnetic force than the sintered ferrite magnet radially oriented by making circular or cylindrical a sheet-shaped resin magnet mainly composed of a rare earth-cobalt alloy based ferromagnetic powder oriented specifically and a resin.
CONSTITUTION: For example, A) rare earth-cobalt alloy based magnetic powder (e.g. samarium cobalt, cerium cobalt or the like) and a resin (e.g. chlorinated polyethylene or the like) are melt-mixed in a metal die and a magnetic field exceeding 12,000 gaus, for instance, is applied to the mixture thicknesswise under pressure to form a sheet-shaped resin magnet oriented thicknesswise. The magnet thus formed is made circular or cylindrical by coiling it around a metal or plastic bar.
