Abstract
Deterministic methods studying the losses due to the motion of single Bloch walls or of well defined domain structures yield equations of limited accuracy, which only provide some hints as to the trend of power losses in different materials. These results are compared with the ones obtained through a recently developed statistical treatment of the loss processes, which predicts with good precision hysteresis and dynamic losses vs. frequency and induction, on the basis of a very limited input information.
