Using a wooden stick instead of a nail will increase the number of paper clips that the electromagnet can pick up.
Adding more coils of copper wire to the nail will increase the number of paper clips that the electromagnet can pick up.
Pushing the coils of copper wire closer together will increase the number of paper clips that the electromagnet can pick up.
Using a batter that produces less electric current will increase the number of paper clips that the electromagnet can pick up.
