This is the phenomenon called later "hysteresis," and studied in minute detail by Ewing and others.
Like Newton and the falling apple, Levy and the hysteresis in the warp field.
A well-known example of hysteresis is presented by the case of permanent magnets.
But if such is the case I attribute it solely to the hysteresis and Foucault current losses in the core.
We should expect too—and we find—that hysteresis is more prominent in weak gels than in strong.
In Table V. are given the results of hysteresis tests by Ewing on samples of commercial sheet iron and steel.
The hysteresis losses in iron are so great that an iron core, even if finely subdivided, is heated in an incredibly short time.
If heated to above 135 C., the hysteresis loss soon attains a maximum, but then begins to decrease.
The life warmth of hysteresis pulsed and throbbed along wires and channels.
Certain specimens heated to 160 C. were found to have their hysteresis loss doubled in a few days.
1805, from Greek hysteresis "a coming short, a deficiency."
hysteresis hys·ter·e·sis (hĭs'tə-rē'sĭs)
n. pl. hys·ter·e·ses (-sēz)
The lagging of an effect behind its cause, as when the change in magnetism of a body lags behind changes in the magnetic field.
The dependence of the state of a system on the history of its state. For example, the magnetization of a material such as iron depends not only on the magnetic field it is exposed to but on previous exposures to magnetic fields. This "memory" of previous exposure to magnetism is the working principle in audio tape and hard disk devices. Deformations in the shape of substances that last after the deforming force has been removed, as well as phenomena such as supercooling, are examples of hysteresis.
