A couple of interesting experiments with rotating magnets

Making a device which rotates two magnets which are set at attracting each other
at the highest possible RPM (rates per minute)

Making a device which rotates two magnets which are set at repelling each other
at the highest possible RPM (rates per minute)
-North towards North
-South towards South

And calculating what could happen. And using all kinds of sensors to see what happens.

Extra: Experiments with bigger and stronger magnets and electromagnets.
Extra: Multiple distances. And more.
Extra: Also seeing what happens at a lower RPM.
