Dependence of Dynamic Preisach Distribution Function on Magnetizing Frequencies Paper i proceeding, 2005

The dynamic Preisach distribution function for electrical steel at different magnetizing frequenclies have been determined by the combination of the experimental measurements in Epstein Frame and the method of central cycle curves. The dynamic Preisach distribution function can be considered as a combination of Gauss function (along $\alpha=\beta$ line) and Lorentz function (along $\alpha=-\beta$ line)
