 Some models such as the Preisach model (originally applied to ferromagnetism) and the Bouc–Wen model attempt to capture general features of hysteresis; and there are also phenomenological models for particular phenomena such as the Jiles–Atherton model for ferromagnetism.The term "hysteresis" is derived from , an Ancient Greek word meaning "deficiency" or "lagging behind".It was coined around 1890 by Sir James Alfred Ewing to describe the behaviour of magnetic materials.
