In this paper we will show a procedure developed under MATLAB and LabVIEW software package which is able to simulate the scalar ferromagnetic hysteresis applying the Jiles-Atherton model. The MATLAB realization has been developed to analyze the behaviour of model, the LabVIEW realization has been applied to simulate a toroidal shape core. The measurement system containing the core will be the basis of a controlling algorithm to realize sinusoidal form of the magnetic flux density. © 2006 FEI STU.
