An IPT system magnetic flux pad includes two substantially planar coils (17) in close proximity to each other above a magnetically permeable core (14). The coils (17) each define a pole area (11, 12) and the distance between one or more adjacent turns of the coils (17) located in a region between the pole areas (11, 12) being different from the distance between one or more adjacent turns of the coils (17) located outside the region between the pole areas (11, 12).
