A motor is a coil that the motor effect pushes round and round. One side is pushed up, the other down, so the coil turns. A clever part called the split-ring commutator swaps the current every half turn, so the coil keeps spinning the same way. Turn it up to the target speed, then remove the commutator to see why a motor needs it.

Will the turning effect reach the target?
The coil keeps turning on its own. Set the controls, predict, then take the reading.

More current, a stronger magnet, or more turns gives a bigger turning effect. The split-ring commutator keeps it turning one way.
