Abstract
This invention relates to an anisotropic neodymium-iron-boron system plastic bonded magnet containing from 10 to 20% by weight an anisotropic neodymium-iron boron system magnetic powder having a grain-size distribution from 10 to 49 microns and a resin binder. By employing this constitution, a substantially improved (BH).sub.max of the compressed mold body, due to improved magnetic field orientation, is realized.
