Abstract
Current concepts of the physical origin and mechanisms of losses in magnetic materials are reviewed under three traditional categories: hysteresis losses, eddy-current or dielectric losses, and residual losses. The phenomenological Landau-Lifshitz equation is used to quantitatively express the various manifestations of the residual losses. Possible physical mechanisms contributing to the phenomenologically introduced Landau-Lifshitz damping term are qualitatively discussed
