The proposed model combines tendency for minimization of Gibbs' magnetic energy with the rate-independent maximum-dissipation mechanism that reflects the macroscopic quantity of energy required to change one pole of a magnet to another. This energy can increase within the evolution which is the effect like hardening in plasticity. The microstructure is described on a mesoscopic level in terms of Young measures.
