In the first test, I compared two coils, one very small, and one medium (A and B respectively). The traces for those two mini coils are shown in the second photo. Coil A produced a big dead spot in the middle of the peak of the sine wave due to the magnet being over both legs at the same time and canceling the voltage. Coil B wasn't so bad, but still a noticable dip.
Now, when I compared coils B and C, (medium and large, respectively) we see more intersting results. Only the biggest coil has a nice full peak because there's very little overlap with the magnet covering both legs at the same time. It's tempting to think that we should make great big holes in our coils.
That's not really true though, because a real coil has many turns, not just two. So while part of two legs may be covered by the magnet, the additional copper you can pack in there still gives you more volts and amps out compared to the great big hole coil. Up to a point anyway. Everything involves some compromise. So I wind coils with holes a little smaller than the magnet and cross my fingers.
Have a lovely day.

Honestly, I see nothing wrong with what your saying here. But the phrase "not limited too" comes to mind. I have alot of practical experience with "dc waveforms" and I feel due to the .707-141 conversions I think ac waveforms are sometimes abit more tricky. Perhaps it was un-wise for me you say that you are wrong. Just attempt to envision how my mind interpeates an 'ac' waveform. I believe that the dc waveform is the building block of a true sinewave this includes both positive and negative amplitude.(on the respective positions of the zero-line). Hey, troy Id like to compliment you on your co-gen system that your building in you basement, a very intreging project indeed.
