Abstract

Method of manufacturing magnetically anisotropic bodies by magnetically compressing and orienting each other in parallel, magnetically anisotropic particles that are contained in a matrix of non-ferromagnetic or low ferromagnetic material between the poles of an electromagnet and fusing the thus obtained conglomerate to form a compact body, characterized by the fact that at least the ends of the magnetic poles between which the particles are contained, consist of non-ferromagnetic material.
