In some embodiments, a first magnet 1060 and a second magnet 1070 (as shown in FIG. 10B) may similarly be used to couple the power transmitter device 310 and the power receiver device 315. The first magnet 1060 is provided in the flat base portion 1110 of the power transmitter device 310, for example, in the center of the transmitter coil 340 to avoid interference with the magnetic field generated by the transmitter coil 340. The second magnet 1070 is provided in the flat portion 1120 of the power receiver device 315, for example, in the center of the receiver coil 370 to avoid interference with the magnetic field generated by the transmitter coil 340.
Thus, the application provides, among other things, inductive power transfer systems.
