Princeton's WordNet
hysteresis(noun)
the lagging of an effect behind its cause; especially the phenomenon in which the magnetic induction of a ferromagnetic material lags behind the changing magnetic field
Wiktionary
hysteresis(Noun)
A property of a system such that an output value is not a strict function of the corresponding input, but also incorporates some lag, delay, or history dependence, and in particular when the response for a decrease in the input variable is different from the response for an increase. For example, a thermostat with a nominal setpoint of 75u00B0 might switch the controlled heat source on when the temperature drops below 74u00B0, and off when it rises above 76u00B0.
Webster Dictionary
Hysteresis(noun)
a lagging or retardation of the effect, when the forces acting upon a body are changed, as if from velocity or internal friction; a temporary resistance to change from a condition previously induced, observed in magnetism, thermoelectricity, etc., on reversal of polarity
