Shorting coil gives back more power

[Feynman]

I just looked into Rosemary's results today, and I'm not sure what to think yet (the screenshots are too low a resolution), but some of the terms make sense...

Current does not necessarily have to be the flow of electrons.

The other idea is that utilization of the back-EMF / counter-EMF may be promising.  Thane Heins apparently has a device working on this principle... the magnacoaster patent works by 'pinging' an electromagnet in the presence of Biasing magnets... Naudin's 2SGen works similarly via magnetic coupling, etc.

So it seems to me there are a lot of commonalities.-

In terms of future research, I think my plans are to finish winding my electromagnet  (I grabbed a ferrite rod inductor from radio shack, around 5cm long and 1cm in diameter, and I will be winding this with 30awg magnet wire . )

I'm going to pulse the electromagnet with HV pwm pulses and see what sort of waveform I can observe.

The one question I'm wrestling with is whether to wind it monofilar or bifilar, but I bought three of the ferrite rods, so perhaps I will make a couple of different types.

I also bought a couple of soft iron nails so I can experiment with electromagnets which have large eddy currents.

You have seen this but for some others who might be interested here is a peak sine event shorted 8 times. The probe was on x10 so 10 volts per square.

When the coil is shorted at the right peak time the coil sends back lots of power.

   Since this is about coil shorting, I will throw in my toy. I recently found a F&P style motor for $15 us. I just finished "re-programming" it for single coil access. I will be running 12 mags all N around it on a 36 coil stator. The motor will be triggered by a single coil for each phase. The rest of the coils will be out to connectors for ease of use.
   Mounted up the set for a motor run in the next day or so. Then as it progresses, I will start adding the shorting circuits.

On the multi short scope shot, what is the unloaded ac out voltage? Mine is about 10v per coil or 120 per phase. Looking to have 2 coils in each circuit with the left over 3 supplying operating voltage for the shorting power.
