Hysteresis refers to the lagging of the magnetization of a ferromagnetic material like iron. If we place the ferromagnetic materials within a coil of wire carrying an electric current, then the magnetic field which is created by the current causes all of the atomic magnets in the material to align with the field. As a result of this alignment, the total magnetic field increases. This alignment does not occur instantaneously, but in fact lags behind it.
The word hysteresis is also used to describe rate-independent state. It implies that if a certain set of inputs x(t) produce an output Y(t), then the inputs X(αt) produce output Y(αt) for any α > 0.
