Abstract

Abstract Starting from a microscopic model of ferromagnetism, information is deduced about the form of the macroscopic constitutive relationship between the fields H and M; this exhibits hysteresis and space interaction. Accordingly, the concepts of distributed and nondistributed hysteresis functionals are introduced. Constitutive relations of this type are coupled with Maxwell's equations for a distributed system, for both the quasistationary and the fast evolution cases. Several weak formulations in Sobolev spaces are introduced; existence results are proved by means of implicit time discretization, a priori estimates and compactness procedures for taking the limit in the hysteresis functional.
