Abstract

A magnetic flux pad (BPP) is provided for generating or receiving magnetic flux. The pad may be used with an inductive power transfer system, and comprises a magnetically permeable core (4) and two substantially flat overlapping coils (2, 3) magnetically associated with the core (4). The coils (2, 3) are arranged so that there is essentially no mutual coupling between them.
