Oh, and yes also regarding the distance the magnets move but I was quite impressed by how far they do move apart even using the cheap little magnets I used in my investigation.As far as I can see from the drawing, half the length of each groove on the cylinder would have to be exactly equal to the travel experienced by the magnets to produce any actual rotation.
The magnet movement during the attraction phase would/should produce half a revolution, and the repulsion phase should complete the other half.
I suspect you’d need either a tiny cylinder or colossal magnets as I don’t think there would be much magnet movement in real terms.
Here is a pic of my initial test:
I attached two small magnets from a fly screen to a folded business card. You can see that the field holds them at a respectable distance.
