A wireless power transfer (“WPT”) pad with a ferrite chimney is disclosed. The WPT pad includes a winding with a conductor where the conductor is wound in a planar configuration. The winding includes a center section about which the winding is wound. The WPT pad includes a ferrite structure with a parallel section located on a side of the winding with at least a portion in parallel with the winding, and a chimney section in magnetic contact with the parallel section and located in the center section of the winding, the chimney section extending perpendicular to the parallel section.
