Abstract
Methods and apparatus are disclosed for wirelessly transmitting power. In one aspect, an apparatus for wireless transmitting power is provided. The apparatus comprises a first coil loop defining a first area, the first coil loop conducting current at a first current value for generating a first magnetic field. The apparatus further comprises a second coil loop surrounding the first coil loop and defining a second area, the second coil loop conducting current at a second current value generating a second magnetic field, wherein a ratio of the first current value to the first area is substantially equal to a ratio of the second current value to the second area.
