Analytical Functions of Magnetization Curves for High Magnetic Permeability Materials

Abstract

In this paper, combined rational and power functions are used to represent magnetization curves of high magnetic permeability fe rromagnetic materials. The proposed functions cover much wider range of magnetic fields than functions currently used in simulation software packages. The objective is to present simple functions for approximation of magnetization curves with minimum number of unknown constants. The calculated functions are finally compared with measured magnetization curves to validate the pre cision in a wide field range from 10-2 to 10 6 A/m.
