Methodology of creation of ring permanent magnets with radial magnetization from an isotropic alloy of the Sm – Co system with induction coercivity no lower than 280 kA/m is presented. Special attention is devoted to the temperature stability of the magnetic parameters and to the strength characteristics of the alloys studied. A method for magnetization of isotropic ring magnets from Sm – Co-base magnets in radial direction is suggested. Ring permanent magnets with radial magnetization are tested in actual magnetic systems. The characteristics of textured and isotropic magnets are compared.
