Good luck. But this configuration is very unstable, the poles tend to attract and repulse. You cannot make it with a thread i think, you need some good bearings. And once you have the bearings, the forces would be too great, even if there is an effect, again it cannot overcome the friction.

It is not good that way in that the forces are too great i think.

I said, i switched from permanent magnets to experiments with a coil and induction, because my experiments gave me a reason to consider, that no continuous rotation can be achieved with permanent magnets. That there is overunity, but that overunity is too small.
