Automatically-aligning magnetic field system

A wireless power transfer device includes a first transmitting coil oriented along a first axis; a second transmitting coil on the first transmitting coil and oriented along a second axis different from the first axis; a nonmagnetic material magnetically decoupling the first transmitting coil from the second transmitting coil in an area of overlap between the first and second transmitting coils; and a driver configured to separately provide first and second currents to the first and second transmitting coils, respectively, to generate a magnetic field.
