Abstract :
The authors present a new static hysteresis model for magnetic materials based on physical meaning. The idea is original: electronic transformation of the material is compared to a chemical reaction. Then a simple analytic formulation of the B(H) law for GO iron sheet in the rolling direction is obtained. Results are compared with measurements. The model is as simple as the Potter one, its parameters can be easily determined and its accuracy could compete with the Preisach model. Finally an easy computation by finite element software is gained
