ELECTROMAGNETS
... An electromagnet can be made by wrapping insulated copper wire around a nail. Attach a volt battery or power supply to the ends of the wire (be sure to strip the insulation away first) and note the nail’s ability to act like a magnet (i.e., pick up paper clips, etc.) and to react to another magnet b ...
