A wireless power supply and a portable heating device are provided. The wireless power supply includes an electromagnetic shield and the portable heating device includes a magnetic field source. Placement of the magnetic field source proximate the electromagnetic shield can create a local flux window in the electromagnetic shield. The transfer of electromagnetic flux through the local flux window energizes the portable heating device at various locations along the wireless power supply. The effectiveness of the electromagnetic shield is generally maintained away from the flux window, and the electromagnetic shield reduces stray flux that might otherwise damage nearby objects and/or reduce the efficiency of the wireless power supply.
A wireless power supply system comprising:
The wireless power supply system of claim 14 wherein the portable heating device is slidably positionable along the power transfer surface, and wherein the electromagnetic shield and the primary coil are positioned subjacent the power transfer surface opposite of the portable heating device.
