摘要

This paper reviews the classical magneitization models for computational use and proposes information technology (IT, in short) based model for the magnetodynamics in ferromagnetic materials. At first, Fourier model of the hysteretic magnetization is derived. Second, assuming the bar-like domain walls derives a domain-based model. A simple example verifies this validity of domain-based model. Third, a composite model by combining the Preisach with domain-based models is derived as well as Rayleigh's law is derived. Finally, IT based model for magnetodynamics in ferromagnetic materials is introduced.
