In a simple motor, the poles of the magnets are swapped over and the connections to the power supply are swapped over as well. What happens to the rotation of the coil?
It stops, because the two changes cancel each other out completely
It reverses, because the direction of the force on each side reverses
It reverses, because only the direction of the magnetic field matters
It carries on in the same direction as it did before the changes
