Magnets experiment

1 A neodynium magnet you can turn, in the middle,
2 Rings of a certain material fixed, and strong
3 Ferrite magnets that are attracted by the neodynium magnet but not by each other
  Certain sizes might be optimal. and different sizes are interesting.

And turning the neodynium magnet and seeing what happens
And how the magnets turn, and how long it takes for each magnet to do a full round
