Flux coupling device and magnetic structure

Flux coupler includes a core with a magnetically permeable having a first axis, comprises two coils associated in core and magnetically by each coil, and the located first side of the core 1 are polar region that is separated along the axis forming the coil is a central region positioned between the respective pole region, the opposite end region of the central region, the central region and end regions and a side region between the ancillary electrode area is provided beyond the end regions of each coil, the leakage magnetic flux that would be generated from each coil in use in the vicinity of the end regions Absorb. .BACKGROUND 9
