Abstract
A method of making a permanently magnetized, radially anisotropic, sintered and curved body, consisting essentially of a ferrite of the formula Me0.6Fe2O3, in which Me is at least one of the barium, strontium and lead metals, the body having a closed annular shape with an inner diameter that is at least 0.8 times the outer diameter, a method in which a ferrite powder is shaped into the shape of a body molded in a radial magnetic field and then sintered, characterized by that the density of the molded body material is first increased by hydrostatic compression.
