Abstract: The disclosure relates to a method, apparatus and system to wirelessly charge a device. In one embodiment, the disclosure relates to a wireless charging station having a detector to identify presence of a device at or near the charging station that would otherwise be damaged by the magnetic field of the wireless charging station. The detector detects a response signal emitted from the device under charge and determines whether to generate the desired magnetic field to charge the device or to cease the magnetic field to preserve the device from potential damage caused by the magnetic field.

Abstract: Techniques of magnetic field distribution are described herein. The techniques may include forming a wireless charging component including a driving coil to receive a driven current generating a magnetic field. An outer turn of a parasitic coil may be formed, wherein the outer turn is adjacent to the driving coil. An inner turn of the parasitic coil may be formed, wherein an inductive coupling between the driving coil and the parasitic coil generates a redistribution of a portion of the magnetic field at the inner turn.
