It is a temporary magnet made by coiling wire around an iron core; when current flows in the coil the iron becomes a magnet.
To make a simple electromagnet, then, you'll need a source of electricity, a conductor, and metal.
1) Look around the house or check out the hardware store to get the following supplies:
> A large iron nail
> 3 feet (0.9 m) of thin coated copper wire
> A D-cell battery
> Small magnetic objects, like paperclips or pins
> Wire strippers
> Masking tape
> Small bowl made of plastic or wood
2) Strip insulation from the ends of the wire.
3) Set up your supplies in a small bowl made of plastic or wood. It's a good idea to contain the energy you're working with in a bowl that won't conduct electricity.
4) Grasp the wire about 8 inches (20.3 cm) from the end. Position it at the head of the nail and wrap it around the nail. Make a second wrap adjacent to the first one; it should touch the first wrap, but not overlap it. Continue wrapping the nail until you've covered it all the way to the tip.
5) Connect the wire ends to the battery. Wrap the exposed end of one side of the wire around the metal part of the battery on the positive side. Wrap the other exposed end to the negative side of the battery. Place a small piece of masking tape over the wrapped wire on both sides to keep it in place.
6) Test the magnet. Once the wires are attached to the battery and the electricity starts flowing, the nail will become magnetized. Test it by placing it against a paperclip or another small piece of metal. If the nail picks up the metal object, the magnet is working.
