Abstract
This paper reviews the classical magneitization models for computation use, and also proposes information/intelligence 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. This model is verified by a simple example. Third, a composite model by combining the Preisach with domain-based models is derived, and then, Rayleigh's law is derived. Finally, IT based model for magnetodynamics in ferromagnetic materials is introduced.
