1. Make an Electromagnet
You will need a large iron nail, a fresh D size battery, thin coated copper wire (about 3 feet), and some paper clips.
Our last experiment among 15 cool experiments to do at home with household items is not difficult to do and is pretty cool. Wrap the copper wire around the nail leaving about 8 inches of it loose at one end. Next, remove about an inch of the plastic coating from both ends of the wire and attach one end of the wire to one end of the battery (using tape), and the other end of the wire with the other end of the battery. You have made your electromagnet! Now put the point of the nail near some paper clips and observe how it picks them up.
