Definitions

n.名词 noun
  1. 1

    Physics.

    • : the lag in response exhibited by a body in reacting to changes in the forces, especially magnetic forces, affecting it.Compare magnetic hysteresis.
    • : the phenomenon exhibited by a system, often a ferromagnetic or imperfectly elastic material, in which the reaction of the system to changes is dependent upon its past reactions to change.

Examples

  • A well-known example of hysteresis is presented by the case of permanent magnets.

  • The closed figure a c d e a is variously called a hysteresis curve or diagram or loop.

  • The effects of temperature upon hysteresis were also carefully studied, and many hysteresis loops were plotted.

  • Hence in performing a cycle there is a waste of energy corresponding to what has been termed hysteresis-loss.

  • We should expect too—and we find—that hysteresis is more prominent in weak gels than in strong.
