Force of Magnetism - Windows to the Universe

The Spring 2011 issue of The Earth Scientist is focused on modernizing seismology education. Thanks to IRIS, you can download this issue for free as a pdf. Print copies are available in our online store.

The Force of Magnetism

You may ask, how does the force of Magnetism work? The force goes from one pole to another. A pole can be described as the point where the force is pointed.

Most magnets have two poles, as shown in this picture. Planets can have more than two poles. The magnetic field "lines" illustrate where the force of magnetism is, and whether it is stronger (red) or weaker (blue).


This is an illustration of how magnetism works.

Two opposite poles will attract, or pull together.
