simple Electromagnet

COMPONENTS REQUIRED:
A large iron nail (about 3 inches)
About 3 feet of THIN COATED copper wire
A fresh D size battery
Some paper clips or other small magnetic objects

1. Leave about 8 inches of wire loose at one end and wrap most of the rest of the wire around the nail. Try not to overlap the wires.
2. Cut the wire (if needed) so that there is about another 8 inches loose at the other end too.

3. Now remove about an inch of the plastic coating from both ends of the wire and attach the one wire to one end of a battery and the other wire to the other end of the battery. See picture below. (It is best to tape the wires to the battery - be careful though, the wire could get very hot!)

4. Now you have an ELECTROMAGNET! Put the point of the nail near a few paper clips and it should pick them up!
