I needed to create an electromagnet for a project, so I decided to document the steps to show how to create your very own electromagnet.
Warning: The more current you place through the wire, the more heat it will give off and could start a fire if it becomes too hot. The wires will be hot after putting current through them. You can use thicker wires to allow more current. Recommended wire type is copper.
1. Phone Line (or small insulated copper wires such as magnet wire)
2. Wire Stripper
5. D Batteries (power source)
6. Tape or glue
7. Ferrous metal object such as a pipe or nail
8. Small ferrous object to test with (small screw, nail, etc.)
9. Time on your hands
Step 1: Simon says: Strip!!!
1. Strip the phone lines of their outside sheathing. Don't cut into the interior wires. As you move along, you'll need to use the pliers to push the sheathing off. If you can, try to strip at least two to three feet (that's all you'll need to make this simple magnet).
2. Bare the ends of the wires (If you had to cut the wires, bind the bare ends together to create a long wire and place tape over the bare spots). Now take one end and place it up next to the metal object you wish to make into a magnet.
3. Either glue or tape it into position to prevent it from unraveling.
4. Now start wrapping your wire around the metal object as shown in the video below.
