Application of the Preisach model to the calculation of magnetization curves and power losses in ferromagnetic materials

摘要

The ability of Preisach-type scalar models to describe static and dynamic hysteresis properties is discussed. Three aspects are addressed in particular: the description of reversible magnetization processes, the characterization of magnetic interactions, and the calculation of dynamic hysteresis loops. Applications of the standard Preisach model and of the moving Preisach model to the description of Henkel plots in recording media and to the prediction of power losses in metallic soft magnetic materials are discussed.
