Abstract
A wireless powering device comprising a first coil assembly including a first coil and a second coil assembly including a second coil. The second coil is adapted to be electromagnetically coupled with the first coil. One of the first coil and the second coil is used as a transmitting coil and another of the first coil and the second coil is used as a receiving coil. The second coil is movable with respect to the first coil in a direction perpendicular to a direction of magnetic lines generated by the transmitting coil.
