Abstract
The equivalent loss resistance of magnetic cores is analyzed on the basis of magnetic domain theory. The hysteresis resistance due to hysteresis loss is dependent on the variation of the Steinmetz constant. The eddy current resistance due to eddy current loss is strongly affected by the change of domain configurations and is described by an experimental parameter that depends on the number of domain walls, the resistivity of the material, and the dimensions of the core, all of which control the mechanism generating eddy current losses
