A magnetization model for computational magnetodynamics
TLDR
In this paper, a Chua-type magnetization model based on magnetic domain theory is applied to typical ferromagnetic materials, such as iron, ferrite, and amorphous magnetic material.Abstract:
In order to calculate the magnetodynamic fields exactly, it is essential to work out a magnetization model. We have previously proposed a Chua‐type magnetization model based on magnetic domain theory. This Chua‐type model is now applied to typical ferromagnetic materials, such as iron, ferrite, and amorphous magnetic material. As a result, it is revealed that the typical magnetization characteristics of representative ferromagnetic materials can be satisfactory reproduced by our Chua‐type model.read more

A generalized Chua-type vector hysteresis model for both the non-oriented and grain-oriented electrical steel sheets
TL;DR: In this article, a generalized Chua-type vector hysteresis model is proposed to describe both the static and dynamic vector magnetic properties of electrical steel sheets, which takes into account all significant harmonic components of the measured H-waveforms, thus it provides precise prediction of Hwaveforms even under highly saturated magnetic flux densities under alternating, rotating and distorted magnetic fields conditions.
