Design of RLC circuit for pulse magnetizer of permanent magnets

Abstract

The current pulse magnetizing process of permanent magnets is considered. General conditions for the design of a pulse magnetizer are given for the case when the magnetizing process is effected on the magnet put in free space. The boundary-integral analysis of the magnetic field inside the magnet is presented. It concerns both the state corresponding to the maximum value of the magnetizing current pulse and the magnetized state after the full magnetizing.

Boundary‐integral approach to determine the magnetic field created by a permanent magnet put in free space

“…The first example is related to the magnet bank consisting of seven circular strontium-ferrite magnets ( Zycki and Pawluk, 1998). Each singular magnet unit is supposed to be homogeneously magnetized and it is considered as a discretizing layer of the whole bank.…”
