hysteresis heater • Hz 351
hysteresis heater An induction heater in which
heating results from hysteresis loss in the load.
hysteresis loop See HYSTERESIS CURVE.
hysteresis loss Power loss caused by hysteresis in
a magnetic material exposed to an alternating
magnetic field, or in a dielectric material exposed
to an alternating electric field. It is characterized
by the generation of heat.
hysteresis meter An instrument that determines
the hysteresis loss in a ferromagnetic material in
terms of the torque produced when the material
is rotated in a magnetic field, or vice versa.
hysteresis motor A synchronous motor that does
not require direct-current excitation, and does
not have salient poles. It is started by means of
hysteresis losses that the rotating magnetic field
causes in the secondary.
hysteretic constant For a ferromagnetic material,
hysteresis loss in ergs per cubic centimeter of
material per cycle of magnetization.
hysteretic loss See HYSTERESIS LOSS.
hystoroscope A device used to determine the magnetic
characteristics of a material.
Hz Abbreviation of HERTZ.
