By analyzing power loss in Mn-Zn ferrites at the secondary peak temperature of the initial permeability, we were able to obtain the first evidence that eddy current loss coincides with the equation derived from the classical theory of magnetism. By analyzing the dependence of power loss on the electrical resistivity, the power loss can be divided into the contributions of loss factors such as hysteresis loss, eddy current loss and residual loss. The residual loss obtained in this study stands for the loss factor independent of electrical resistivity.
