Definitions for "Core loss"
Energy wasted by hysteresis or eddy currents in the core of an armature, transformer, etc.
Losses caused by a magnetization of the core and its resistance to magnetic flux.
Power dissipated when any conductor, particularly a ferromagnetic core, is subject to a time-varying magnetic field.
Keywords:  drawn, input, winding, load, even
