  • Abstract
    The anhysteretic magnetization Man depends on the internal field after degaussing Han and, possibly, on the demagnetization factor N. Neel´s theory of the N dependence is criticized. Classes of Preisach models are identified for which Man (Han) does not depend on N. A numerical method is presented to determine Man (Han, N) from a Preisach model. The zero-field anhysteretic permeability is expressed in terms of the Preisach distribution up to first order in N-k, where k is the parameter of the moving Preisach model
