PROBLEM TO BE SOLVED: To enable obtaining magnetic powder having superior characteristics and higher mechanical strength by mixing a resin, containing a viscosity- adjusting agent which is effective for reducing the resin viscosity with rare earth magnetic particles. SOLUTION: The anisotropic rare earth element bond magnetic powder produced by mixing Sm2 Co17 powder with a viscosity-adjusting agent which is effective for reducing the resin viscosity within the range of 10-15wt.% with respect to the resin. For the resin viscosity, the viscosity prior to containing the viscosity-adjusting agent, i.e., the viscosity at the normal temperature (25 deg.C) of the resin proper exceeds 300 poise, furthermore, the viscosity at the normal temperature (25 deg.C) of the resin to be mixed in the state of containing the viscosity adjusting agent, i.e., immediately before mixing with the Sm2 Co17 , does not exceed 50 poise. Later, the produced bond magnetic is molded in the magnetic field, to produce a magnet molded body. |
