Theory of ferromagnetic hysteresis: determination of model parameters from experimental hysteresis loops

The authors describe how the parameters defining hysteresis in the theory of hysteresis can be obtained from a set of experimental magnetization measurements. The hysteresis parameters can be calculated from the anhysteretic susceptibility at the origin, the coercivity, the remanence, and the coordinates of the hysteresis loop tip. The ability to calculate the hysteresis parameters from a set of experimental data is a key step in the process of utilization of the hysteresis model. The algorithm that has been developed successfully determines the values of the parameters to within a few percent in most cases.<
