- n. The lagging of an effect behind its cause, as when the change in magnetism of a body lags behind changes in the magnetic field.

- n. 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°.

- n. 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.

- n. A lagging of one of two related phenomena behind the other.

- n. 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
Such systems often exhibit hysteresis, that is multiple states for the same system parameters but which state you are in depends on history, i.e., initial conditions.
The ice sheet's so-called hysteresis, or resistance to change, is now in doubt.
This intermediate input region is a deadspace where there is no response, a property called hysteresis, it is like backlash in a mechanical linkage.
If high sensitivity is required the hysteresis is a problem, but in many circuits it is a helpful property.
Economists use the term "hysteresis" to describe this dynamic in which the longer workers are jobless, the more their skills erode.
In 1986, Summers wrote an influential paper about 'hysteresis' in unemployment.
Summers won't say it, but short of a total remake of "free market" economics, likely nothing and perhaps that's America's future with growing millions consigned to a permanent underclass, while an elite few at the top grow richer, until one day "hysteresis" snaps the system in a disruptive convulsion, the old model passes from the scene, and nothing is the same again.
The moisture content in equilibrium with a given relative humidity is also affected by the so-called 'hysteresis' effect.
"degenerative syndrome" called hysteresis that causes marble to expand more than it should.
Economists call this "hysteresis": it means that a recession can be more than a cyclical phenomenon, and have long-lasting effects.
