The answer is A. Could someone please explain this to me? Thank you in advance!
A long single coil of wire is connected directly to an ammeter which is used to indicate the direction of the current in the wire. As the N-pole of a bar magnet is inserted into the left-hand end of the coil, the ammeter indicates a current in a certain direction.
Which other action, performed separately, produces a current in the same direction?
A inserting the S-pole of the magnet into the right-hand end of the coil
B withdrawing the N-pole of the magnet from the left-hand end of the coil
C inserting the S-pole of the magnet into the left-hand end of the coil
D withdrawing the S-pole of the magnet from the right-hand end of the coil
E inserting the N-pole of the magnet into the right-hand end of the coil
