1. one kind is used for the method manufacturing hybrid magnet (20), including step:

  • A () provides the powder (10,10'"'"') of the granule (11,11'"'"') including at least two magnetic materials (12,12'"'"'), wherein, instituteState powder (10,10'"'"') as corresponding in the mixture of at least two magnetic materials (12,12'"'"') or at least two magnetic materialsA kind of separate powder exists,B () is powder particle (11,11'"'"') the application diamagnetism of the separate of at least two magnetic materials (12,12'"'"') or mixingOr paramagnetic coating material (17,17'"'"'),C the mixture forming of the granule of application (13,13'"'"') is become molded body (19) by (),D () is in the temperature less than the temperature being suitable for sintered magnetic material (12,12'"'"'), turning coating material (17,17'"'"')Carry out for sinter coating material in the case of delivering in the unbodied substrate (21) of diamagnetic or paramagnetic material (22)The heat treatment of material (17,17'"'"'), this substrate embeds the granule of at least two magnetic materials (12,12'"'"'), andE () magnetizes at least two magnetic materials (12,12'"'"') in external magnetic field,Wherein, in succession or in any combination execution step (c), (d) and (e) simultaneously in any order.
