Not sure I understand that vid.  Are the disks on the same side of the magnet? Why do they counter rotate? Is one disk reacting off of the other to counter rotate?


Mags

No
It dosnt matter what side of the disc the wires are on, the force will still be in the same direction as we are dealing with circles.
The disc spin in opposite directions because one wire is the positive, and the other wire is the negative-the current flows are in different directions, an thus so is the rotations.

Yeah, I understand that the wire can contact the disk anywhere on the outer perimeter to get the same results.

And now I understand that one disk has current running opposite of the other.

Interesting , I wonder why he cut the spirals into the discs', where Tesla said to put raised ridges on the disk in a spiral pattern?
If he just motored one disc , could he collect off the other?
Thanks for linking that video ,got some ideas to try.

Oh dear.

I don't have any copper plate to try this, would aluminum plate work?
It must have something to do with the eddy currents.
Gravok, I skimmed your link and will read later, Thanks for that.
How much potential can be generated with this type of set-up?
The heavier the copper ,the more amps?

I would need to see that to believe it.   If you take 2 disk mags and have them face each other say 1in apart, and the magnets are set up do they can spin on axis, if you spin one, the other wont spin. There is zero force on the other magnet to spin with the other.

Likewise, we cant get the disk magnet to spin using dc through a wire, no matter the position or orientation of that current carrying wire. The field from the wire will only affect the magnet as a whole, not as if the field lines are teeth of a gear and torques the magnet into rotation.

The key idea of having the ring magnet mounted to the copper disk in a homo polar dynamo is the fact that the magnet rotates with the disk yet the disk still produces current. But if we mount a magnet to the end of a coil and move the magnet and coil through space, what ever direction, we get no current in the coil. So the solid ring magnet mounted to the copper disk and when they rotate together, current is produced in the disk, is a very very special case in point.   

The very foundation of that destroys the idea that there are no field lines along with the idea of change in field strength on a conductor is needed to produce mutually inducted currents in the conductor.

But this is pretty much the only special case for that argument. At least that I know of.

What attracts me to the idea of having the ring magnet attached to the rotating copper disk is the possibility of no drag when currents are sent to a load..  Typical gens need increase in input as the load increases. But here with the magnet spinning with the disk, if we draw current from the disk, is there a need for more input torque to overcome drag/lenz? And if so, with the mag spinning with the disk, what is causing the drag if the 2 components are mounted and spinning as one?

So say if there is no drag. Is that the secret to a true lenzless gen? And if there is drag, what are we dragging against? The field itself, as these fields are all around us?  If so, then that is possibly the holy grail of solid state motion devices. If we can drag against it, then we should be able to produce motion with it by pushing and/or pulling against it, like a silent ufo, car, plane, etc.
