In this history worksheet, students use the questions to discover meaningful science and history connections. The worksheet is meant to be viewed online to access individual answers.

Students explore various types of electromagnetic waves, the range of the spectrum, and common sources of electromagnetic waves.

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.

A great introduction to magnetic domains, including pictures which illustrate the effect on domains caused by external applied magnetic fields.

The Barkhausen effect makes the concept of magnetic domains audible (if not exactly music to the ear).

[Free Registration/Login may be required to access all resource tools.] Looks at magnetic materials and the structure and breadth of a magnetic field. The concept of magnetic domains is explained, and how they behave in a magnetic field....

In this interactive unit students will see how magnets work and how they are used in some of the most useful and common devices today.

This site is an introduction to magnetic domains, including a picture showing distinct domains taken through a process called "Magnetic force microscopy."

Think iron, nickel and other "ferromagnetic" substances are the only ones with magnetic properties? In fact, everything reacts to magnetic fields in some way.

A series of pages which define key terms and explain basic concepts related to magnetism. A set of practice problems with answers and solutions are given. Links to related internet resources and a list of animations are provided.

Wikipedia.com provides an excellent introductory site on magnets. Including basic information describing different types of magnets and their characteristics.

What is magnetism? Learn about magnetic domains, how magnets attract or repel, magnetic materials, electromagnets and their uses, and the history of magnets.

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.

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...

A great introduction to magnetic domains, including pictures which illustrate the effect on domains caused by external applied magnetic fields.

This site from Integrated Publishing provides three different examples of theories of magnetism.

Join a group of middle-school students on a visit to a laboratory at the Massachusetts Institute of Technology, where they experiment with "mystery mud" and learn about the relationships between magnetism, particle motion, and changes in...

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.

View a computer model simulation from NOVA Online that illustrates what happens during a magnetic field reversal, an infrequent occurrence that may be currently underway.

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.

A brief definition of the Curie temperature for ferromagnetic materials.

In this What's Up in the Environment? video segment, an electrical engineer in Virginia and his 13-year-old son explain how they produce electricity in their home. [3:58]
