1. An IPT system magnetic flux pad for generating or receiving a. magnetic flux, the pad comprising:
- two substantially planar coils in close proximity to each other and being magnetically associated with a magnetically permeable core, the coils each defining a pole area and a distance between one or more adjacent turns of the coils located in a region between the pole areas being different from a distance between one or more adjacent turns of the coils located outside the region between the pole areas.

Abstract
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).

24. An IPT system magnetic flux receiver pad comprising:
-
two substantially planar coils in close proximity to each other and being magnetically associated with a magnetically permeable core; and a further substantially planar coil overlapping the other two coils, and the coils being. wound such that an impedance is reflected onto a flux transmission structure which compensates for a change in an inductance of the transmission structure due to a presence of the receiver pad. - View Dependent Claims (26, 27, 28, 40, 41, 42, 43, 44)
