hysteresis
(1) the phenomenon that the magnetic state of a substance is dependent
upon its magnetic history, so that its magnetization for an increasing
magnetizing force differs from that for a decreasing magnetizing force.
(2) the characteristic of magnetic materials that causes the trajectory of the flux density vs. field intensity curve as the intensity is increased to be different from that when the intensity is decreased, giving rise to a loss, which is proportional to the area enclosed by the two trajectories.
