When a magnetic field is applied perpendicular to the flow of current, the field causes resistance in the current. This is the Lorentz force at work, and can be observed well in the Hall effect. (Java tutorial)

Learn about the Lorentz force with the help of this tutorial, in which a wire fashioned into a pendulum moves inside a magnetic field. (Java tutorial)

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

William Thomson, known as Lord Kelvin, was one of the most eminent scientists of the nineteenth century and is best known today for inventing the international system of absolute temperature that bears his name. He made contributions to...

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

See how electricity and magnetism interact with this activity. Activity has students creating a current by swinging a copper coil through a magnetic field. The copper coil will start a second coil swinging as well.

An activity where students test different materials to see which allow magnetic lines of force to pass through them and which block the magnetic lines of force.

The MagLab has its own machine shop, complete with an experienced, talented staff. These craftsmen collaborate closely with renowned scientists to create one-of-a-kind magnet parts that make possible experiments done nowhere else in the...

Students simulate magnetic pole reversal to study the movement of Earth's magnetic poles.

Make predictions and observations to determine the cause and effect relationship between magnets and magnetic and nonmagnetic items in seven out of nine objects.

Third graders will be able to identify objects that are attracted or repelled by magnetism.

Use the engineering design process to create a solution to problem involving magnets?

Recreate the discovery by Hans Christian Oersted about the relationship between electricity and magnetism in this very simple experiment.

Given diagrams, illustrations, or descriptions, students will identify examples of electric and magnetic forces.

This is a ten-question quiz pertaining to magnetism.

Create a magnetic field that is stronger than Earth so a compass needle will orient itself to the new field in this activity.

Use the 5E model to explore magnets.

Explains what magnetism and gravity are and the differences between them.

In this lesson, 5th graders will create a painting based on the action paintings by Jackson Pollock. Instead of dripping and splattering, the paint will be moved using a metal object, such as a paper clip, along with a magnet.

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...

Here is a lengthy listing of activities and resources pertaining to magnets and magnetism. Experiments which can be performed with many different types of magnets are described; detailed directions and photos are provided.

[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....

Gives a simple description of the theory of magnetism and the properties of a magnet. Very good descriptions for beginning level.

Students complete a series of six short investigations involving magnets to learn more about their properties. Students also discuss engineering uses for magnets and brainstorm examples of magnets in use in their everyday lives.
