“…However, these have not been made clear. For the tapewound ring core, which is a basic shape and is used as a magnetic device in various measuring instruments and electrical apparatus, the authors have previously shown the fundamental items of the relations between the core dimension ratio and the ac magnetic properties in the case of basic magnetizing conditions of commercial frequency and sinusoidal voltage [2]. Moreover, we have also reported the relations between the magnetizing conditions and the ac magnetic properties for excitation by a distorted-wave voltage [3].…”
