Magnetic Hysteresis
Magnetic Hysteresis. A magnetic hysteresis, otherwise known as a hysteresis loop, is a representation of the magnetizing force (H) versus the magnetic flux density (B) of a ferromagnetic material. The curvature of the hysteresis is characteristic of the type of material being observed and can vary in size and shape (i.e. narrow or wide).

Domain-wall energy and hysteresis loss in ferromagnetic material
Physics. 1966. 213. It is shown that the extinction of a domain wall and its subsequent reappearance during changes in the magnetisation of a ferromagnetic material is an irreversible process in which domain-wall energy is converted to heat. It is suggested that this energy is a substantial component of the observed static hysteresis loss.
