This is a magnetic motor where depending on the current direction will make the motor spin clockwise or counter clockwise. Depending on how much current was going through the fast the inside will turn. But when under those the current will begin to arc and a build up of carbon will block current going through.
Electric motor: The way we made this was shaving off the coat off one end and shave half another end. What happens when the ring becomes horizontal it will stop because it has no magnetic field. Shaving half will make the ring have some momentum to continue spinning.
This experiment related the magnetic field due to current. The three point were when the two currents would flow in different directions, one current flowing in one direction, and both going in the same direction. The direction of the magnetic field was determined by a compass. For the two currents in opposite directions the compass pointed north meaning no deflection. One current was deflected to the right ,as well as the two currents going in the same direction deflected also
