Abstract
Starting from description of quasi-static hysteresis using Preisach model, a complex quasi-static susceptibility (permeability) can be introduced. Based on this assumption, the correlation between static (frequency independent) W stat and dynamical (frequency dependent) W dyn part of total losses via complex permeability is shown. Consequently, non-linear frequency depedeence W dyn (f) can be explained including a convenient distribution fucction of relaxation parameters into the model.
