N-machine theory tested

In Craigy's device, the disc is larger than the magnets and is not totally contained within the magnetic field of the magnets.  Wouldn't this cause eddy currents in the disc which could be responsible for the fluctuations in voltage?

The lathe has current flowing through the rotor.  I think I had the misfortune of being electrocuted by one once.  I worked on them at one point, they're quite unpredictable.

AS a matter of fact, I think something should be done about that fact, they're quite dangerous at high speeds...  the rotor is acting like an HPG, in fact.

No it only produces dc, the video was made in haste without thinking too much about the pickup points or brushes, i was just doing it to see the faraday parado

Half an hour after filming i fiddled some more by putting a wire to the tailstock of the lathe and could get almost 2 volts at 3000 rpm. I should have short circuited it , but didn´t. again used a bearing on the end of a probe for disc pickup.

I don´t have any more Ali , although the disc should really be copper but can´t get that here in the canaries.

You should check the rim of the rotor as well.

GB the point I'm trying to show is that there MIGHT be a polarity shift depending on where you measure. I attached an illustration of this below that should explain it. The question is if we keep on increasing the radius of the tapping point on the disc will there be a point of voltage reversal where the part of the disc going from the radius of the magnet to "infinity" overrules the voltage going from the center of the disc to the radius of the magnet...if so we can eliminate back torque. This can be easilly tried out with a setup like Craigy's with a sufficiently big disc plate a few times bigger than the magnet. I might perform this experiment as well with cardboard and tinfoil as my disc.

I tried another experiment where I routed a wire going from the outer edge of the PM going to the its center and then out. When high current was flowing through the wire, there was a force on the wire to force it to rotate, as expected, but there was *no* force on the magnet.

If the N-machine is COP>1, then it must be due to another effect. The current flowing through the metal does not produce a counter opposing force on the magnet.

This other effect might be due to the rotating magnetic field, as Bruce claims inertia changes (and perhaps other things) from rotating objects.
