Abstract

In this article the relation between the material parameters appearing in the Preisach model and those entering the Jiles-Atherton model is discussed. Emphasis is on the variation of the anhysteretic curve and on the magnetization dependency of the pinning parameter, when changing the Preisach distribution function. The discussion rests upon the consideration of the shape of the MH loop on the one hand and upon the identification of the instantaneous loss dissipation on the other hand. The techniques outlined are applied to silicon iron alloys and are compared with results from measurements.
