1. A magnetic flux pad having a front face and a back face for generating or receiving magnetic flux in or from a space beyond the front face, the pad comprising:
- two pole areas for sending or receiving flux,a magnetically permeable core,two coils magnetically associated with the core,whereby the flux enters the pad at one of the pole areas and exits the pad at the other pole area.

Abstract
A magnetic flux pad for receiving or generating magnetic flux. The pad includes two pole areas (11, 12) associated with a magnetically permeable core 14. Coils 17 define the pole areas. The pad allows useable flux to be generated at a significant height above a surface of the pad.

12. A magnetic flux pad having a front face and back face for generating a magnetic flux in a space beyond the front face of the pad, the pad comprising:
-
two pole areas for sending or receiving flux, a magnetically permeable core, two coils associated with the core and being provided on a side of the core adjacent to the front face of the pad, whereby the pad produces an arch shaped flux in the space such that essentially each line flux starts on one of the pole areas, arches to the second pole area and joins on itself through the core with essentially no flux present at the back face of the pad.

13. A magnetic flux pad having a front face and back face for receiving a magnetic flux from a space beyond the front face of the pad, the pad comprising:
-
two pole areas for sending or receiving flux, a magnetically permeable core, two coils associated with the core and being provided on a side of the core adjacent to the front face of the pad and adapted to receive a horizontal flux component, and a further coil magnetically associated with the core and adapted to receive a vertical flux component.
