Definition

Energy converted to heat inside a magnetic material during cyclic magnetization, produced by irreversible or dissipative processes that make magnetic flux density B lag behind the applied magnetic field H; quantitatively proportional to the area enclosed by the material's B–H loop per cycle and the magnetic volume.
