Homework Statement
Hi, I've been trying to figure this out for days. I've wrapped an insulated wire that I got at Lowe's around a large metal nail. I then connected it to a knife switch and a 9v battery (per the directions). The nail is supposed to pick up 30 paperclips. I've tried wrapping the wire very tightly and more loosely, but nothing helps.
Thanks in advance,
Marie
