Abstract :
It is shown that, in the case of abrupt (sharp) magnetic transitions, eddy current hysteresis can be represented in terms of the classical Preisach model. In this representation, memory effects are taken into account by the structure of the Preisach model, while dynamic effects are accounted for by a special form of the input to the model. A startling consequence of this representation is the fact that nonlinear dynamic eddy current hysteresis can be fully characterized by its step response
