Abstract
A new approach to the problem of power loss calculation in ferromagnets is provided, which takes into account the effect of the irreversible jumps of the Bloch walls during magnetization. The magnetization process of the material under cyclical conditions is treated as a random function of time and separated into two components: a) a periodic component which gives rise to a line spectrum and is related to the classical dynamic loss; b) a random component which has a continuous power spectrum and which is responsible for both the total static loss and the anomalous dynamic loss. Bloch walls correlation effects are discussed in relation to the change of this last component and its related losses under different physical conditions.Keywords
