Abstract
The present invention relates to ferrite particles for bonded magnets having a bulk density of not more than 0.75 g/cmand a degree of compaction of not less than 65%, a resin composition for bonded magnets using the ferrite particles and the composition, and a rotor. The ferrite particles for bonded magnets and the resin composition for bonded magnets according to the present invention are capable of providing a bonded magnet molded product having a good tensile elongation and an excellent magnetic properties.
