Latest: No back torque generator.

Good thinking. Yes you can do that! Sorry about the misery you had to endure  . The cool thing about what you just suggested is that you can make a complete radial set but that's for later. For now just keep add as much as you like. But use electrical tape around the windings to keep the windings nicely packed together.

Edit: Oh yeah remember to hook all the windings in parallel or you end up canceling everything. The current has to go in the same direction where the conductors meet. See below.

You did mean ofcourse to hook them up in series, not parallell. You just wind one coil, and continue with the other coil using the very same wire but winding the next counterdirectional to the first one, etc., etc.. This will automaticly end up in having the wire going in the directions as you whish.

@Broli ,
 

The magnetic field is a property of space/aether or w/e you want to call it. This is the absolute reference frame. Imagine taking a snapshot at some given time from this outside frame of reference and analyzing all the velocity vectors and then calcultating the forces.

I believe this is wrong! The magnetic field is a property of the electron spin in the atoms of the magnetic material generating it.
The field is directly attached to the magnet! If you spin the magnet you spin the field.
The homopolar generator works with the disk attached to the magnet because in this case the current is generated in the external circuit.
Your idea is the same as not spinning anything and still collecting the current in the windings and this just don't work.

How does that make sense to you? The external circuit just provides a path for the current to flow due to the EMF on the attached disk. If this path was attached to the magnet as well no current would flow. Because again if you analyze the velocity vectors the path will induce an EMF now that will cancel out the EMF induced on the disk. I don't see why this is so hard to understand.

If you don't believe me setup the disk and magnets and spin them attached to each other. Then use some electrostatic "compass" to show you that the rim of the disk will be more positively or negatively charged due to the electrostatic induction that has taken place caused by the induced EMF.

Yes it seems absurd that there's a local EMF even if from the local frame's point of view there's no relative movement. But to me that's as absurd as why the homopolar motor/generator works.

@Broli,

I have a setup that I built just for that purpose. It can test spinning just the disk, spinning just the magnet, spinning the disk and the magnet, spinning the external brushes, spinning the disk and brushes, spinning a magnet and a disk in opposite directions.

I have already tested all the combination's! I can tell you that spinning the magnet does spin the magnetic field. It is hard to know the field is spinning but I know how to prove this.

@ Broli,

Because again if you analyze the velocity vectors the path will induce an EMF now that will cancel out the EMF induced on the disk.

In the case where the disk and magnet rotate together, the disk is simply a conductor in the same frame as the magnet and is not breaking any lines of force and all the current is generated in the external conductors that are being cut by the rotating magnet. This is 0% on disk 100% from external circuit.
The faster the magnet and disk rotate, the more is generated.
