Abstract

A vector hysteresis modeling algorithm is suggested to model the hysteresis phenomena of an isotropic magnetic material. The algorithm combines the Stoner-Wohlfarth and Preisach models. The vector property of each single domain magnetic particle with uniaxial anisotropy, which is supposed to constitute the magnetic material, when the direction and magnitude of applied field are changed is modelled by using the Stoner-Wohlfarth model. The coercive and interaction fields of each particle are modeled by using the Preisach model. In the algorithm the easy axes are assumed randomly distributed over all possible directions. The algorithm reduces to a scalar Preisach model if only one easy axis is defined. The developed algorithm is applied to the analysis of the magnetization of the isotropic rubber ferrite permanent magnet, and the result is compared with experiments
