the lag in a variable property of a system with respect to the effect producing it as this effect varies, esp the phenomenon in which the magnetic flux density of a ferromagnetic material lags behind the changing external magnetic field strength

Hysteresis is something that happens with magnetic materials so that, if a varying magnetizing signal is applied, the resulting magnetism that is created follows the applied signal, but with a delay.
Hysteresis means that the magnitude of a resulting quantity is different during increases inthe magnitude of the cause than during decreases, due to internal friction in a substance.
As a general term, hysteresis means a lag between input and output in a system upon a change in direction.
