Two Rodin Coils shown making neodymium disc magnets rotate. AC current, approximately 12 volts. Brown coil is 18 AWG, blue/white is 24 AWG. The configuration of magnets is: a few stacked together with a ball bearing on the top, these taped to the coil to keep them in place. Then a lesser number of discs are placed on the bearing so that the poles are repelling against the stack underneath. The attraction to the bearing is just enough to counter the repulsion. Vibration is intense, and it wants to spin. Note, there is very little torque. Neat, eh?
