To increase the number of paper clips that the electromagnet can pick up, the student should add another battery. This action increases the current flowing through the wire, enhancing the strength of the magnetic field generated by the electromagnet.
Replacing the iron nail with a plastic spoon or reducing the number of turns would not help, as both would reduce the effectiveness of the electromagnet. Decreasing the current would also weaken the magnetic field.
