The present disclosure aims to provide a bonded magnet having good magnetic properties and a method of preparing the bonded magnet. The present disclosure provides a method of preparing a bonded magnet, including: a first compression step of compressing a magnetic powder having an average particle size of 10 .Math.m or less while magnetically orienting it to obtain a first molded article; a second compression step of bringing the first molded article into contact with a thermosetting resin having a viscosity of 200 mPa.Math.s or less, followed by compression to obtain a second molded article; and a heat treatment step of heat treating the second molded article.

An anisotropic bonded magnet and a preparation method thereof are provided. By stacking magnets having different magnetic properties and/or densities, the magnets in the middle have high properties and the magnets at two ends and/or the periphery have low properties, thereby compensating for a property deviation caused by a difference in pressing densities during a pressing process, and improving the property uniformity of the magnets in an axial direction. The method solves the problem of “low in the middle and high at two ends” caused by the phenomenon of non-uniform magnetic field orientation and density along a height direction during orientation and densification.
