[Free Registration/Login may be required to access all resource tools.] Discusses what a magnetic field reversal is and the evidence that this has happened with the Earth.

In this interactive tutorial students will explore magnetic force. Students will observe interactions of magnets and study magnetic fields. The source of magnetic properties is believed to be moving charge. Since moving charge produces...

In this science fair project, use Google Earth to determine if large mammals align themselves in respect to the earth's magnetic field. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...

Learn what magnetic fields are and how to calculate them with this reference page.

Did you know that not all trains run on tracks? Some of the world's fastest trains are magnetic levitation trains (maglev). This means that the carriage of the train is suspended over the rails with no support, but only with magnetic...

An electromagnetic simulation which replicates moving charged particles in two identical magnetic fields separated by a zero magnetic field gap.

A bar magnet model built by placing a group of magnetic dipoles along the magnet. This simulation shows the magnetic field of a bar magnet, and has a movable compass which shows the magnetic field values.

A unit all about magnets! Explore magnetic forces, types of magnets, and more through these informative activities.

[Free Registration/Login may be required to access all resource tools.] The Earth's magnetic field and how it protects life on Earth, and how it is used for navigation.

[Free Registration/Login may be required to access all resource tools.] Examines Earth's magnetic field.

A module that uses pictures, videos, reading passages, and review question to go over what a magnet and magnetic pole are, and how magnetic force is related to magnetic field. This site may require free registration to access all...

This comprehensive study guide covers the main terms and concepts needed for an earth science unit on the earth's shape and magnetic field. Review questions are included at the bottom of the study guide.

[Free Registration/Login may be required to access all resource tools.] Examines Earth's magnetic field.

Move a bar magnet or an electromagnet around to see how the magnetic fields change. Requires Java.

You can use a bar magnet and a compass to get a rough idea of the strength of Earth's magnetic field. Read this article to find out how!

See drawing from Hans Christian Orsted's lab notebook showing an experiment in which an electric charge passing through a wire seemed to create a magnetic field!

A simulation which shows the field of a magnetic dipole or quadrupole using compass needles indicating direction and relative field strength. Change the angular orientation of the dipole, and a movable compass shows the magnetic field...

[Free Registration/Login may be required to access all resource tools.] Looks at the properties of magnets and why some materials are magnetic.

Explore what an electric field is and how electric fields interact with this module. Module includes a video, interactive activity, and review questions.

Help students explore Earth's magnetic field with this soda bottle magnetometer activity. Follow links to other space projects for the classroom.

In this interactive tutorial students will explore how a magnetic field affects a current-carrying wire and also how two current-carrying wires affect each other. They will learn about Biot-Savart, Ampere's Law and the magnetic field...

The human body has an impressive ability to heal itself after injury, but humans have nothing on planaria. Planaria have an amazing ability to regenerate. An entire animal can regenerate from just a fraction of the body. This project...

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.

In this activity discover the direction of the magnetic field by making patterns of the field visible with iron filings.
