Abstract

A power receiving coil and a measuring coil are in a power receiving device. The measuring coil is inductively coupled to the power receiving coil. Concentric turns of a wire in the measuring coil are around a common axis. Also around the common axis are concentric turns of a wire in the power receiving coil. At least one of the concentric turns of the wire in the measuring coil is closer to the common axis than each of the concentric turns of the wire in the power receiving coil. A power feeding device receives a control signal from the power receiving device. The control signal instructs the power feeding device to adjust a power level of an electromagnetic wave emission.
