another way to fight lorentz

A homopolar generator is in fact a faraday disk, the modernized version that is, as he did not have the modern magnets that we do, ...

The idea here is that it was Faraday's paradox, not Lenz's.

Frankly, following Newman's ideas makes the situation appear more meaningful...what with the gyroscopic particles and everything.

There have always been arguments about where the reference frame is, and for simplicity it the wire, just for the fact that it's not moving.  I suppose current flows out because it would rather not stay in, it provide a point of exit for the electrons, acquiring it requires sending it back in though, at the center.

This changes however, if you place the magnetic field perpendicular to the axis rather than parallel to the axis, (or through it).  I took two magnets and oriented them so that they were sitting ( diagonally ) one face north up, the other south up, they were attracted at each others rim, I then suspended a copper sheet over them which I had cut into a circle and conducted electricity across the diagonal of the disk.

It spun.

Just as a faraday or homopolar disk would if it had ONE magnet below it, the disk rotates instead with two.  Here is a diagram. Crude as it may be.  It demonstrates the perpendicularity of the forces.  The disk will spin depending upon the path it takes across the magnets, N-S or S-N, etc.

very interesting jadaro

did you spin the disc and try to generate anything? there would still be an issue with brushes but it could be applied to my machine

I'm afraid I'm lacking a rigid setup to do so, and lacking the tools on top of this, the money as well, otherwise I would do such a setup.  But I'm sure that what you ask will indeed produce a current, however small it may be, the possibility is that it will produce twice the voltage potential as has been mentioned as a standard HPG or Faraday disk.

I've often though that you could simply use roller skate bearings, something round that spins and makes contact with the periphery without much friction.  This is far different than the usual carbon brushes.

The bearings can be acquired cheaply, the disk is an issue for me, and it's size and tolerances are as well.  I'm a fully capable machinist with no tool and no machines,  .

Anyway, I've read that a demonstration with a bearing motor was performed, it functions similarly to the diametric model above, but on multiple smaller scales, the roller bearing would probably not detract from the effects seen here.

EDIT: of course the magnets are stationary in these experiments.

On another note, if you try to generate with a radial using a single side of the magnet, and then use a radial to send current back to the axis, it will cancel out the effects, it is symmetrical with regard to this.  The over all effect of the current is seen only by the radial path, and not say, if you were to spiral outward and radial back, the effect would still cancel, it is only the radial path from the axis to the point of brush contact on the outside which causes the rotation.

This is why I performed the experiment in question.

EDIT: ..this setup will work all the same, as the path of the current crosses the magnetic field, the disk will rotate perpendicular.  It is as if to say, that the atoms conducting experience a force in such a way as to compel them to push on their neighbors, as if atoms would rather not conduct electricity.  SO the path is constantly being replaced with new atoms and the point of rotation is at the point where north and south merge in the disk, which I should hope is the logically placed axis of rotation ( center of gravity of the disk ).

its ingenious that you use conductive bearings instead of brushes, i don't know why i never thought of that but i would imagine it cuts out on friction a lot

where do you plan on going with your design? im interested to hear it
