Here's a variation that obtains spin enhancement. The image shows a toroidal core in cross section with a single turn input. There is a two turn output, one of the turns being primarily a piece of Fe wire. This wire is magnetized by having a PM at each end. The second turn of copper wire, as well as passing through the transformer core, also winds around the Fe wire in bucking coils configuration. The load current flowing through these bucking coils adds to the Fe wire magnetization at one end and subtracts at the other end, thus creating a magnetic gradient along the wire. The spin polarized electrons in the Fe wire then gain an additional pull, the output voltage increases slightly. We are talking only microvolts increase here, tens of microvolts at the most, so this might only be useful at small voltage levels and high current. But a transformer that increases its output voltage as you increase the load current could be interesting.
