Homopolar Generators (N-Machine) by Bruce de Palma

I would find it very strange if your first rendering actually caused the magnet to rotate. This would mean an instant violation of many things. Can you show the experiment?

A force applied at any point on a body in equilibrium results in an equal and parallel reactive force at the centre of mass of the body acting in the direction of the applied force.

This reaction causes such linear motion of the body as would occur if the original force were applied at the centre of mass, independent of any rotational motion produced by the moment of the applied force.

For additonal information, please see the thread on the Paradox Engine created by Tusk at http://www.overunity.com/13102/the-paradox-engine/#.VP0CnPROmSw

Also, remember that electrons moving perpendicular through a magnetic field are deflected, while electrons moving parallel through a magnetic field are accelerated.

The video by Mags is also empirical proof that our kinetic energy equation is wrong.

The reason I find the possible operation of this strange is that in this kind of operation there should in theory be no induced EMF as you go from rim to rim.

I totally agree that their should be no induced EMF from rim to rim.  In other words, I see this working as a motor, but not working as a generator.

Ah...OK, I think I see it now. The magnet on the foil isn't rotating like a homopolar  motor, it's trying to slide, like a railgun armature, and the sliding friction makes it rotate. I think.

So if you had, say, a brass tube that would be a good fit for the OD of the magnet, or even better just a long skinny cylinder magnet polled endwise, and you set it onto a pair of rails and then supplied current to the rails, it would scoot down the rails and also roll. Maybe.

I am in full agreement with your proposed analysis.  The  reactive force being applied to the center of mass induces a linear movement which causes rotation as it slides across the surface.


I believe we can easily convert this linear movement into a rotation to be used as a motor instead of a railgun by using the principals of the Paradox Engine ( video:  https://www.youtube.com/watch?v=dG8YOp_njFs ).
