Making an Electromagnet

This electromagnet is easy to make, and can be powered from any small battery, such as "AA" or 9 volt batteries. DO NOT USE ANYTHING LARGER! It's pretty powerful, and it will eat up batteries quickly if used a lot, especially if used continuously. If it's getting warm, turn it off and let it cool down.

Wait a minute! That's the same picture that was on the simple generator page! Yup. Most of this paragraph is the same too! This is another demonstration of the connection between electricity and magnetism. If we move electricity through the wires wrapped around the bolt, it makes an electromagnet. If we move a magnetic field through the wire wraps, we make electricity! Neat, huh?
