A student wraps 10 coils of copper wire around an iron bolt, and then she connects the ends of the wire to a battery. Next, the student uses the nail to lift paper clips. She then conducts a second trial using the same wire, battery, and nail, but with 30 coils of copper wire wrapped around the bolt.
