@Scotty1  Yes you are correct, I have done this test myself and it is interesting that the bottom magnet can be anything and still not rotate.

I believe that the lines of force DO indeed rotate with the magnet but do not affect other objects simply because the amplitude does not change so not actual work is applied as we perceive it.

I think in your demonstration that the lines of force lines of the rotating magnet simply attract to the nearest force line on the stationary magnet in an effort to conserve energy as they always do.

So they simply continue to disconnect and reconnect and do no actual work to the bottom magnet.
The test setup I described earlier may possibly confirm this principal.

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.

What I meant was that in a faraday disc, the magnet and the collector can be stationary. And the eddycurrents that appears in a rotating metal disc between the stationary magnets can be taken partialy out by the stationary collector. Some part HAVE to rotate to take out energy. If both disc an magnet are stationary, the collector must move relative to these, and the current appears in the collector, and use the disc as a conductor to close the loop - instead of generating currents in the rotating disc and use the collector as a conductor to close the loop. It is pretty much the same thing.

I do not believe that an LED will lit in @brolis experiment by rotating a magnet with a fixed coil on it where the LED is connected to. But it is worth a try. I have a 30mm neodisc with a small hole in center to attach a screw. So I can use a dremel to spin the magnet with the coil on it. I have LED's too that I can solder to the coil. If I get a rotating light, I will tell.

Oke noone told me hot glue is useless on ferrite magnets, it comes right off due to their smooth surface, so I can't form a big magnet with these small ones. Any ideas?

Gorilla glue

Takes a while to harden but holds like a weld. I've used it on many types of magnets and it's only problem is it is almost impossible to remove the magnet once it dries.

CA should do. Clean all surfaces, add some CA activator on one part, let it dry, have CA on the other part. Put them together, and there you go.

Can't you just use two barmagnets magnetized through thickness, snapped together in the ends so you get opposite polarity on both sides - like the disc you showed, and let the exsess vindings go outside in thin air instead along the edge of the round magnet? So only the parallell windings are going along the bar magnet. That should in theory do the very same thing.
