Noun

1. 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 75° might switch the controlled heat source on when the temperature drops below 74°, and off when it rises above 76°.
2. Magnetic friction in [[dynamos]], by which every reversal of magnetism in the iron causes [[dissipation]] of [[energy]].
