Abstract

In this article, the energy balance equation in the original Jiles-Atherton model is revisited. In particular, the assumption that the energy stored in a lossy material is equal to that stored in a lossless material is removed. This modification results in more accurate prediction of B -H trajectories. A new approach to characterize material parameters based on resonant response is also set forth. Extensive experimental validation is provided and model parameters for several common materials are given.
