Abstract

The energy dissipated by a magnetic material is computed for both a single particle and an assembly of particles represented by a generalized Preisach model. For an isolated particle, the two components of the energy loss are due to sudden change in the irreversible magnetization and due to the change in the ability of the magnetization to store energy because of the change in state. The former loss is equal to the product of the permeability, the applied field, and the discontinuous magnetization change. It is noted that the size of the discontinuous change in magnetization is generally not equal to the difference of the two remanent magnetizations. These energy loss components carry over into the computation for an assembly of particles
