Abstract: A wireless charging system including a transmitter and a receiver. The transmitter is formed of a coil of wire that includes a first loop portion, a second loop portion, and a crossing portion. The crossing portion electrically couples the first loop portion and the second loop portion such that when current is generated in the coil, electrical current flows through the first loop portion in a different rotational direction than in the second loop portion. The receiver is formed of a ferromagnetic core and multiple (e.g., three) coils disposed about the ferromagnetic core. Each coil may be disposed about a different axis of the core such that current may be induced in at least one of the coils by a magnetic field in any direction.
