Electromagnet

Today, the 21st of August, 2008, I made a screw into a magnet by using electric current.

I did this by twisting copper wire around the screw. The copper wire could not touch itself because if it did, it would not work. Then I put electrical tape around the ends so that it would not give me a shock when I was holding it. Then I put the ends of the wire onto the ends of a battery and this made the screw into a magnet. Then I tried picking up some safety pins with the magnet and it worked. The wire got hot.

After that, I got a bigger magnet and used it on the bottom of my truck so when I drive around, I can pick up safety pins and other metal things which are lying around.
