Hi Jones, You wrote: There could even be two coils - one to power the load(by inductance) and one for applying a low energy RF field - as many permalloy-type materials and ferrites have RF-triggered variable magnetic permeability.
Do you have any references concerning "RF-triggered variable magnetic permeability". I have been working on methods for variable reluctance overunity for many years with some suggestive but not completely convincing results. I would be interested in trying other permeability varying techniques such as RF excitation if the variation in permeability is greater than 10%. George Holz Varitronics Systems
