1. An IPT track arrangement comprising:
at least one inverter, the at least one inverter including a first inverter; and
at least one conductor, the at least one conductor including a first conductor electrically connected to the first inverter, wherein
the at least one conductor forms at least a first loop and a second loop of the IPT track arrangement, the first loop and the second loop located adjacent one another and in a plane, the first loop having a first portion that is parallel and adjacent to a second portion of the second loop,
the IPT track arrangement is configured so that respective polarity of current flow in the adjacent first and second portions of the loops is the same, wherein the respective polarity of current flow in the adjacent first and second portions of the loops results in a reduction of an opposition of magnetic flux between the first and second conductor portions,
the at least one inverter includes a second inverter,
the at least one conductor includes a second conductor, the second conductor electrically connected to the second inverter,
the second conductor forms at least a third loop, the third loop having a third portion, a portion of the first loop being parallel and adjacent to the third portion,
the first inverter provides first current to the first conductor,
the second inverter provides second current to the second conductor, and
at least one of:
the IPT track arrangement is configured so that when the first and second currents are out of phase as to each other, the respective polarities of the respective current flows in the third portion and the portion of the first loop parallel and adjacent to the third portion are the same; or
the IPT track arrangement is configured so that when the first and second currents are in phase as to each other, the respective polarities of the respective current flows in the third portion and the portion of the first loop parallel and adjacent to the third portion are the same.
