Abstract

Magnetic resonance coupling, proposed in 2007, was shown to achieve high efficiency and high power at a large air gap. However, the difference between electromagnetic induction and this phenomenon has been called into question. Through many achievements in research, including the proposal of an equivalent circuit model, a unifying explanation of electromagnetic induction and magnetic resonance coupling was shown to exist. Based on these discoveries, the difference between electromagnetic induction and magnetic resonance coupling will be explained.
