ABSTRACT:
A planar-type magnetic structure in which two coils, on two poles of the same core, are separated by an open space which is wide enough and low enough that the air return flux, through the open space, completes the flux circuit for each coil. Thus the coupling coefficient between the two coils is very small, even though they are both mounted on a single continuous core of high-permeability material.
