Really? Perhaps I misread it. What I thought he did was saturate the core via a static applied external field, which reduces its permeability and consequently the measured inductance of the coil. So, he measured a "genuine" difference in inductance. And the windings are toroidal, so you won't get an induced charge on them from the approaching magnet, save as a consequence of core saturation and concomitant nonlinear behavior. As for the changing inductance in the changing external magnetic field, I don't think that happens while the power's on, because the core's being held in a saturated state by the field from the coil. All in all, the pieces which are apparently missing are still careful measurement (or calculation) of power in/out during coil turn on/turn off, and measurement of heat generated in the cores. But, come to think of it, I may be completely confused from A-Z about this. (Yes, it does occur to me, occasionally, that I might be wrong...) > > They know damn good and well they are obfuscating.
