Electromagnetic Lab
Turns out, all you need to make a magnet is a battery, a copper wire, and a nail. I got nailed (no pun intended) with the lovely Christian Harris, and prepared to get my hands electric with a homemade electromagnetic magnet. The point of this experiment was to explain the connections and differences between electricity and magnetism. If we attach one end of the copper wire to the north side of the battery, and wrap it around the nail around a hundred times, without overlaps, nothing will happen. But, if we attach the other end of the copper wire to the south side of the battery, two things will happen. You will very likely receive a minor shock, and, the nail will become magnetized. I tried at first to touch the paperclips to the wire, wondering why the paperclips weren't sticking. It took us forty minutes to figure it out. When we make all the electrons flowing through the wire go the same way, the nail becomes magnetized. YAAAA!~@!@PU*!P@P*U
