Magic of Magnets Teacher Plans - Spartanburg School District 2
... 1. To make an electromagnet, you need an iron nail, some wire, and a dry cell. Wrap the wire around the nail, leaving a few inches of wire at each end to connect to the dry cell. The more wraps, the strong the magnetic force. 2. An electromagnet can be turned on and off. That means you can control t ...
