Answer:
Student A is correct.
Explanation:
An electromagnet can be defined as the magnet that is produced by the electric current passing through a wire surrounding a metal piece. In an electric motor, magnets surrounds the the coil carrying currents. Because of the magnetic field, the current carrying coil experiences a force and it starts to rotate. Thus the electric motors uses the forces between the electromagnets to start running.
Therefore, student A is correct.
