Follow these steps. 1. Leaving about 8 inches of wire loose at one end wrap the wire around the nail make 5 wraps. Try not to overlap the wire at any point. 2. Connect each end of the wire to an end of the battery by taping it in place. (See diagram above). 3. See how many small paperclips your battery can pick up. Record this in your electromagnet data table. 4. Repeat step 3 two more times. Then take an average of the number of paperclips. 5. Disconnect the battery and make an additional 5 wraps of the wire, for a total of 10 wraps. 6. See how many small paperclips your battery can pick up. Record this in your electromagnet data table. 7. Repeat step 6 two more times. Then take an average of the number of paperclips. 8. Disconnect the battery and make an additional 5 wraps, for a total of 15 wraps. 9. See how many small paperclips your battery can pick up. Record this in your electromagnet data table. 10. Repeat step 9 two more times. Then take an average of the number of paperclips.​
