Abstract

The present invention provides a magnetic flux pad for generating or receiving magnetic flux comprising at least three coils positioned such that the windings thereof are in substantially the same plane and a power supply or pickup controller operable to selectively energise or receive power from two or more of the coils such that a magnetic field is produced or received by at least one of a plurality of pairs of the at least three coils. In preferred embodiments the three or more coils are substantially mutually decoupled overlapping and/or equidistantly spaced from one another.
