Students identify magnetism and describe its meaning. Students discuss different types of magnets and list various ways magnets can be used. Students record observations of each magnet, like and different, and whether one has a larger...

Students, in groups, study how a magnet works and how people use the Earth's magnetic field to orient themselves.

This site from the Georgia State University provides a good overview of ferromagnetic materials, introducing concepts such as magnetic domains, hysteresis, the curie temperature, and magnetostriction.

Molecular Expressions at Florida State University offers a java applet to show the a working AC generator.

This site from the Georgia State University provides a brief introduction to diamagnetism, explaining how Lenz's law accounts for diamagnetic behavior in all materials.

This Wikipedia site is an introduction to paramagnetism and paramagnetic materials.

This site from Wikipedia provides a wonderful in-depth explanation of ferromagnetism, covering the atomic behavior which is responsible for ferromagnetic properties. Also introduces the concepts of magnetic domains and the Curie...

This site from the Georgia State University provides a brief introduction to paramagnetism, explaining how paramagnetic materials exhibit magnetization proportional to an applied magnetic field according to Curie's law.
