Abstract
Jiles-Atherton model equations was used in many ways to describe the hysteresis loops of ferromagnetic, ferroelectric and piezoelectric materials. The main advantage of this model is establishing a connection between the hysteresis loop and the physical parameters of magnetic materials. In this study, the magnetic hysteresis curve was presented by using the finite element method and the COMSOL code. The Jiles-Atherton model equations was used to simulate the hysteresis loop, magnetic flux density and magnetic field components in the software. The purpose of this study, while examining the Jiles-Atherton model equations, is to know the effect of changes in the physical parameters of the magnetic material on the magnetic hysteresis curve. The obtained results indicate the changes in the area of the hysteresis loop, the characteristic values of this loop, the changes in the magnetic flux density and the components of the magnetic field by increasing or decreasing the parameters of the Jiles-Atherton model. The decrease in the area of the hysteresis loop and the decrease in the characteristic values of this loop is a reason for changing the behavior of the ferromagnetic material towards soft magnetization and reducing the interaction of the magnetic domains of the ferromagnetic material and vice versa.
