Notes:
A differential dynamic Preisach model developed by us and introduced as an idea suggested by Bertotti is generalized. The starting point of this model is that the instantaneous excess field due to the moving and dynamic processes can be approximated as a function of M and it's variation rate dM/dt: F(M,dM/dt). Thus, we determine a differential equation for the magnetic susceptibility. The model's parameters are found by an original identification method. As an application we simulate a simple electrical circuit and compare the results with the experimental data. A very good agreement between the measured and simulated data is observed. © 1998 American Institute of Physics.
