1. An adapting device configured to interface a wireless power transmitter having a first array of magnets arranged around a source coil in the wireless power transmitter with a wireless power receiver lacking a corresponding array of magnets arranged around a receiver coil in the wireless power receiver, the adapting device comprising:
a planar dielectric substrate;
a second array of magnets embedded in the substrate, having a polarization opposite to the first array of magnets, and configured to contain a magnetic flux formed by the first and second array of magnets to the wireless power transmitter and the adapting device and to inhibit magnetic saturation of receiver coil magnetic shielding arranged around the receiver coil by the first array of magnets; and
adapting device magnetic shielding embedded in the substrate interposed between the second array of magnets and the wireless power receiver when the receiver is placed on or near the wireless power transmitter.
