Diego wants to make an electromagnet for the science fair. He only has a nail, copper wire, and a 9-volt battery. His experiment is to make a magnet strong enough to pick up paper clips. He wants to prove that his magnet can pick up the most clips.
What can Diego do to his magnet to make sure he picks up the most paper clips?

Diego can wrap a few coils of the wire, far apart, around the nail.

To make his electromagnet strong enough to pick up the most paper clips, Diego should choose the option:
Diego can wrap many coils of the wire, close together, around the nail.
Wrapping the wire in many coils close together increases the magnetic field strength, making the electromagnet more effective at picking up objects like paper clips.
