A coil of wire is connected to a very sensitive ammeter that can deflect the needle both ways, indicating the direction of the current. A north pole of a magnet is moved towards the coil before coming to rest inside it. The needle of the ammeter initially deflects to the right. What happens next? A. The needle of the ammeter remains deflected to the right B. The needle of the ammeter deflects to the left C. The needle of the ammeter returns to zero
