초록

A great deal of external magnetic variation is required to demagnetize a magnetic material. In order to analyze a demagnetization model, hysteresis is employed and the best numerical analysis technique so far, regarding hysteresis, is Preisach model. In general, Preisach model, however, bears the instability problem with respect to convergence and hence in this paper, a method adopting M-B variables is proposed to solve the problem. In addition, comparison is made between the experimental MTF equipment and the hysteresis modeling technique for the purpose of developing an effective demagnetization protocol.
