How can electricity be used to make a magnet?

In this experiment you used electricity to make a temporary magnet, called an electromagnet.

When the electricity was turned off, the magnetizing cause was no longer present, so the object was not attracted to the iron crane. So, let's see how electricity is able to make a magnet.
