very simple magnet motor

[xpenzif]

This is a nice idea, however I don't think it will work.
I believe the rotor would default to the position depicted here:

Obviously the magnet prefers the thicker metal, so it will take work to spin the rotor to a thinner part; the same or more work than generated by the initial attraction of the thicker part. Basically, all work done by the magnet has to be undone.

But don't let me discourage you

Hi Iadcw  and Konduct,

Kindly inquire on any progress you may have made since then on the interesting simple magnet motor you both showed drawings and a video animation.

Thanks
