He should reduce the number of turns.
He should reduce the number of turns.

He should add another battery.

Answer 1

To increase the number of paper clips the electromagnet can pick up, the student should add another battery. This action will increase the current flowing through the wire, which in turn strengthens the magnetic field produced by the electromagnet.

Therefore, the correct choice is: He should add another battery.
