### What is an electromagnet?

160 Chapter 10 Figure 10.8: The simplest electromagnet uses a coil of wire, often wrapped around some iron or steel. In the picture, the arrows indicate the direction of current.

### The Strength of Electromagnets

One way to make a temporary magnet is to pass an electric current through a wire wrapped around a core made of a magnetic substance, such as an iron nail. This is called an electromagnet.
