Troy,
This is a very well thought out and executed experiment. It should answer a lot of questions. Dans, shouldn't this have a dedicated page in the experiments section somewhere ?

Quite interesting, its always nice to be able to compare different outcomes of a unique test. What was your magnet spacing? ( basically the gap between them). I tend to run them close or even touching at times but don't tend to use as many turns of wire as everyone else does...
Anyway, Keep up the great work... all will learn from this.

Have Fun!

mag spacing (none / 0) (#6)

Hey thanks Ed,

The neos were spaced pretty far apart. I could fit 24+ around the outer edge of each rotor, and have only 12 in there now. It's a money thing, hmmm, 24 big neos on each rotor at so much per magnet, and pretty soon we're talkin' some real money.

I think I will end up with a compromise of 14 or 16 neos per rotor.

Best Regards,

troy

Great work, Troy. This is the kind of work that really advances this science.

Money issues aside, the wider spacing will actually give better results than would more magnets with closer spacing, due to leakage flux and voltage cancellation.
