N-machine theory tested

[PaulLowrance]

It appears Craigy's device is producing AC.

Most of that is most likely due to contact voltages and the contact changing. If he would just place a 0.1ohm resistor across the voltage meter and make a lot better contact (perhaps from graphite brushes) then it would go away.

PL can you illustrate your latest experiment, I have a hard time understanding what you mean.

[PaulLowrance]

In the 1st experiment the current flowed through the NdFeB magnet from inner to outer edge. I wanted to do the same thing, except have the current separate from the magnet. So in the 2nd experiment the placed a wire that routes from the battery to the center of the magnet (perpendicular), then when the wire almost touches the magnet it routes parallel to the magnet to the magnets outer edge, and from there it goes to the batteries other terminal.

There was a rotational torque on the wire, but there was absolutely no rotational torque on the magnet.

So I think whatever N-machine effect there might be, it's something else other than what Bruce told me.

Does the below illustration show what you did? If so are you 100% positive the whole circuit if allows to rotate on a free axle rotates? This alone is something substational, I recommend you redo the experiment attaching the circuit to an axle so it can rotate.

[PaulLowrance]

I don't have the equipment to put it on an axle right now. My NdFeB magnet is not even 1" in diameter. Maybe a bit over 1/2" diameter.

BTW, anyone trying these experiments should use magnets with high coercivity such as NdFeB. Ceramic magnets due terrible when they're thin because of their low coercivity.
