Abstract :
This paper presents an application of the finite-element method codes developed to design the magnetizing fixtures for isotropic magnets when in situ magnetization is required. The radial, pseudoradial, and multipole magnetization of the surface mounted and interior magnet assemblies are considered. On several case studies, it is demonstrated how accurate modeling of magnetization can be effectively employed for design of permanent-magnet assemblies.
