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.


Problems Research Can the strength of an electromagnet be changed by changing the voltage of the power source? Can the strength of an electromagnet be changed by changing the amount of wire wrapped around its core?
