Electromagnet
What You Need:
A large iron nail.
Around 3 feet if THIN COATED copper wire.
A fresh D size battery.
A couple paper clips or other small magnetic objects.
What to do:
1.Leave around 8 inches of wire loose at one end and wrap most of the rest of it around the nail. Try not to overlap the wire.
2. Cut the wire so that there is around 8 inches left on the other end also.
3. Now you must remove around 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 above. It is best to tape the wire to the battery, but be careful because the wire could become very HOT.
4. Now you should have an electromagnet! Put the point if the nail near a couple paper clips and it should easily pick them up!
NOTE: Making an electromagnet used the battery up pretty quickly which explains why the battery may become very warm, So disconnect the wires after you have finished exploring.
