A method suitable for solving the magnetic field of permanent magnet and energized coil system

This paper introduces a method based on MFS software to solve the fusion magnetic system of permanent magnet and energized coil. The basic idea of this method is to solve the magnetic field generated by the energized coil through analytical methods first, then save the result and add it as the electromagnetic base to the solution result of the coercive force of the permanent magnet material, as the influence exerted on the permanent magnet material, and then By solving the magnetic field of the permanent magnet system by the finite element method, the magnetic field of the permanent magnet and electromagnetic fusion magnetic system can be obtained.
