Abstract:
The amorphous alloys have many bases, Fe-B based alloys are the superlative representatives of the traditional metallic glass systems which have many applications according to the soft magnetic features. They have been an extensive research area for periods in the world because of their physical properties and structures. The researches were based on the addition of a diversity of elements into the Fe-B based alloys. There are many methods for determining physically and mathematically the hysteresis curve for soft magnetic materials. Jiles_Atherton theory of ferromagnetic hysteresis is one approach used in transient modeling of electromagnetics. Since the theory introduced several models developed based on this theory. In this article we shall summarize the model that has been implemented and we shall implement a model in MATLAB and Simulink environment for soft magnetic material by two approaches, the classical and modified Jiles-Atherton model. Presented results indicates that the best approach to modeling the magnetic hysteresis loop is with the modified model equation that also corresponds well with the result of physical experimental measurements.
