  2. Hysteresis - Wikipedia

    en.wikipedia.org/wiki/Hysteresis

    The curves form a hysteresis loop. Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past. Plots of a single component of the moment often form a loop or hysteresis curve, where there are ...

  3. Hysteresivity - Wikipedia

    en.wikipedia.org/wiki/Hysteresivity

    Hysteresivity derives from “hysteresis”, meaning “lag”. It is the tendency to react slowly to an outside force, or to not return completely to its original state. Whereas the area within a hysteresis loop represents energy dissipated to heat and is an extensive quantity with units of energy, the hysteresivity represents the fraction of the elastic energy that is lost to heat, and is an ...

  4. Magnetic hysteresis - Wikipedia

    en.wikipedia.org/wiki/Magnetic_hysteresis

    Magnetic hysteresis occurs when an external magnetic field is applied to a ferromagnet such as iron and the atomic dipoles align themselves with it. Even when the field is removed, part of the alignment will be retained: the material has become magnetized .

  5. Alternative stable state - Wikipedia

    en.wikipedia.org/wiki/Alternative_stable_state

    Hysteresis is an important concept in alternative stable state theory. In this ecological context, hysteresis refers to the existence of different stable states under the same variables or parameters. Hysteresis can be explained by "path-dependency", in which the equilibrium point for the trajectory of "A → B" is different from for "B → A ...

  6. Skin effect - Wikipedia

    en.wikipedia.org/wiki/Skin_effect

    One full wavelength in the conductor requires 2 π skin depths, at which point the current density is attenuated to e −2 π (1.87×10 −3, or −54.6 dB) of its surface value. The wavelength in the conductor is much shorter than the wavelength in vacuum , or equivalently, the phase velocity in a conductor is very much slower than the speed ...

  7. Hysterical strength - Wikipedia

    en.wikipedia.org/wiki/Hysterical_strength

    The most common anecdotal examples based on hearsay are of parents lifting vehicles to rescue their children, and when people are in life-and-death situations. Periods of increased strength are short-lived, usually no longer than a few minutes, and might lead to muscle injuries and exhaustion later.

  8. Shock absorber - Wikipedia

    en.wikipedia.org/wiki/Shock_absorber

    Hysteresis of structural material, for example the compression of rubber disks, stretching of rubber bands and cords, bending of steel springs, or twisting of torsion bars. Hysteresis is the tendency for otherwise elastic materials to rebound with less force than was required to deform them. Simple vehicles with no separate shock absorbers are ...
