Popis:	When an alternating current flows through a ferromagnetic wire, its thermal output is higher than predicted by the familiar Joule law. An additional contribution arises from the heat liberated due to the hysteresis loss in the self-induced magnetic field inside the wire. Simple calculations, based on the formulae derived here, show that in some cases this contribution may be comparable to, or even larger than, the Joule heat.
