• noun a delay in the response of an object to changes in the forces acting on it, especially magnetic forces
  • A phenomenon in which an induced or observed effect remains after the inducing cause is removed. In this way, two physical quantities are related in a manner that depends on whether one is increasing or decreasing with respect to the other. There are various examples, including magnetic hysteresis, electric hysteresis, and thermal hysteresis.
  • A phenomenon in which the changes in the magnetization induced in a ferromagnetic material lag behind the changes in the magnetizing force. This phenomenon is observed below the curie point. Also called magnetic hysteresis.
  • Any phenomenon in which there is a lag between the cause and the induced or observed effect. For instance, the output of an instrument depending on whether the input resulted from an increase or a decrease from the previous value. Another example is the manner in which a thermostat utilizes the right amount of hysteresis to maintain the desired temperature. Too little hysteresis would result in constant switching between cycles, and too much would allow too large a temperature interval between cycles.
  • In an oscillator, an effect in which a given value of a functional parameter may result in multiple values of output power and/or frequency.
