Using the axial connection was the next step but was a bit more involved and this is the test.

Using two large ring magnets placed face to face in attraction with one stationary on one rotating.
On the rotating magnet is the disk, and on the face of the stationary magnet are the brushes.

The connection to the brushes run close to the face of the stationary magnet to shield them from the field of the rotating magnet, then to a center connector and out through the center of the stationary magnet.

This will either continue to output a current as normal OR it will output virtually nothing because all the output comes from the rotating field crossing the brush leads like any conventional generator.

This is also what I think. There must be a relative motion between the coil and the magnet....

It's not what I meant. There is no need of a relative motion between the coil and the magnet (in Faraday disk, it doesn't change anything the magnet to be rotating or at rest).
There is need of a circuit in two parts with a relative motion between them in order charges in one side see the others moving in the B field thus submitted to the Lorentz force.
In F=q*v|B, v is the speed of charge relative to the observer. It is not the speed of charge relative to the source of the B field.

Hey Lumen.
Here is my clip to show the field does not rotate in the setup you describe...2 ring magnets in attraction..one spinning.

I don't think Broli's idea will make current if the wires spin with the magnet because the wires will not cut any flux.
In Broli's drawing the flux lines will be in motion with the magnet and so will the wires..so no current is made.
It can't be like a Homopolar, because the poles spin aound a secondary axis and not their own axis.
Only when the pole rotates on its own axis is there no rotation of the flux lines (see my clip)...then Broli's wires would cut the lines of force.

Of course I could be wrong..

Replace the magnets in my design with an elctro-magnet. Then calculate the Lorentz force or the ampere force and see what you get. Even if the conductor is rotating with the magnet that conductors secondaryvelocity due to the rotation will create a magnet field that will interact with the magnetic field of the magnets. This is not bound to obseravle law. It's like having two wires in parallel atrracting.

I ordered these magnets which arrived today:

So now I'll have the painstacking fun of sticking them to each other to form a bigger rectanglular magnet.

It should'nt be long Broli,just like a detective story.
