1. A magnetic flux device configured to transmit magnetic flux to or to receive magnetic flux from a space beyond the device, the device comprising:

  • at least a first electrically conductive coil and a second electrically conductive coil, the first coil substantially planar, having a first inner periphery bounding a first region, and having a first outer periphery bounding a first area, the first outer periphery having at least one substantially straight first portion, the second coil substantially planar, having a second inner periphery bounding a second region, and having a second outer periphery bounding a second area, the second outer periphery having at least one substantially straight second portion, the second coil substantially coplanar with the first coil; and

    a magnetically permeable material having a substantially planar surface and having a third outer periphery bounding a third area, the first coil and the second coil substantially parallel to the substantially planar surface, the third area extending beyond the first area along the at least one substantially straight first portion and beyond the second area along the at least one substantially straight second portion, the magnetically permeable material substantially overlaying the first region and substantially overlaying the second region.
