After all, there is no better way to learn about a temporary magnet than to see one with your own eyes. You can see temporary magnetism in action at your own desk. Will 5G Impact Our Cell Phone Plans (or Our Health?! Ways to Demagnetize a Magnet. As soon as the field is removed, however, the magnetism is lost. For example when a permanent magnet is placed in contact with another magnetic material like iron, they will always be attracted to each other AND a north and south pole are induced in the other magnetic material. Temporary magnets are much different than the everyday magnet that you might be used to, due to the fact that they rely on outside forces in order to create their own magnetic field. On the other hand, you can think of some of the most basic materials that you might use everyday as temporary magnets. Non- electromagnetic temporary magnets tend to be made of soft magnetic materials, like annealed iron or steel. An electromagnet is a temporary magnet. When the external force is removed from the temporary magnet, it is no longer magnetic. While the details and characteristics of temporary magnets were described in the previous section, permanent magnets are worth mentioning as well.
