Teach Engineering: Drawing Magnetic Fields
Students use a compass and a permanent magnet to trace the magnetic field lines produced by the magnet. By positioning the compass in enough spots around the magnet, the overall magnet field will be evident from the collection of arrows...

Teach Engineering: Magnetic Fields
Students visualize the magnetic field of a strong permanent magnet using a compass. The lesson begins with an analogy to the effect of the Earth's magnetic field on a compass. Students see the connection that the compass simply responds...

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.
Georgia State University
Georgia State University: Hyper Physics: Magnetic Domains
A great introduction to magnetic domains, including pictures which illustrate the effect on domains caused by external applied magnetic fields.
National High Magnetic Field Laboratory
Magnet Academy: Magnetic Domains
In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. That's why you can magnetize them. See how it works in this Java tutorial.
