Abstract

An apparatus, comprising: a first transmitting coil including at least one first portion and at least one second portion, the first and second portions having different polarities; and a second transmitting coil that is disposed above or below the first transmitting coil, the second transmitting coil including at least one third portion and at least one fourth portion, the third and fourth portions having different polarities, wherein the first and second transmitting coils are configured so that, when the first transmitting coil is not driven and the second transmitting coil is driven, a net magnetic flux through at least one of the first portions is approximately zero, the net magnetic flux being a magnetic flux that is entirely attributable to the second transmitting coil.
