Study and modeling of ferromagnetic hysteresis

In this paper we are interested in the study and modeling of ferromagnetic hysteresis. We simulated the magnetic hysteresis based on the Jiles-Atherton (J-A) model that we have developed using Matlab-Simulink environment. The (J-A) model is based on physical considerations, it is characterized by five parameters and considered to our knowledge as the most accurate and complete one. It allows studying a wide range of ferromagnetic material hysteresis loops which justify in this work our choice for this model. In order to determine these five model parameters, we have to numerically analyze experimental data from the material hysteresis loop. For this purpose we applied the (J-A) model for the dynamic study of a magnetic circuit taking into account the phenomenon of hysteretic material.
