There is a secret mysterious force in your home right this very moment! Try these activities to first identify that force and then extend your knowledge of the force by investigating the other activities provided.

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]

This tutorial reviews over electrical energy.

Investigate Faraday's law and how a changing magnetic flux can produce a flow of electricity!

The Canada Science and Technology Museum tells the history of recorded sound. Learn about the hundreds of sound recording devices in the museum's archives. These are grouped into four main categories: Acoustical-Mechanical Systems,...

Batteries are expensive to purchase in a store, but you can make one your self for exactly 24 cents. In this experiment, you will make your own voltaic pile using pennies and nickels and determine how many coins in a pile will make the...

Electrical currents and voltage are defined and illustrated.

Students teams each use a bar magnet, sheet of paper and iron shavings to reveal the field lines as they travel around a magnet. They repeat the activity with an electromagnet made by wrapping thin wire around a nail and connecting...

Use your knowledge of physics concepts like electricity, reflection, magnetism, etc. to complete interactive online puzzles.

Using plastic straws, wire, batteries and iron nails, student teams build and test two versions of electromagnets-one with and one without an iron nail at its core. They test each magnet's ability pick up loose staples, which reveals the...

Build your own windmill and see how the wind can be converted into energy to produce electricity. This science fair project should help you understand the use of wind as a source of alternative energy. The Science Buddies project ideas...

A solid summary from the University of Oregon of the work of James Maxwell Clerk, Michael Faraday, and others in the field of electric and magnetic phenomena. This is a fine essay.

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

Explains electromagnetism, the difference between a permanent magnet and an electromagnet, uses of electromagnetism, and steps for making a simple electromagnet.

Instructional module focusing on light and electromagnetism. Discussion includes historical discoveries that led to the understanding of the electromagnetic spectrum. Site also includes an interactive practice quiz and links relating to...

A large complete authoritative biography of Coulomb. Five large pictures, over a dozen links to contemporaries, references, a poster, other mathematicians. A fine source.

Written by Paul Falstad, these educational Java applets address myriad concepts related to electrostatics, magnetostatics and electrodynamics. You'll find instructions on how to operate each applet, but little explanatory material.

This unit allows students to investigate the cause of a speaker's vibration in addition to the effect.

One of the "Episodes in Romantic Science," this is as complete as a biography gets without being a book. Includes great information about Oersted and his electromagnetic work, The definitive source. Heavily footnoted with many additional...

This lesson introduces students to the role of electricity and magnetism as they build a speaker. In addition, students explore properties of magnets, create an electromagnet, and determine the direction of a magnetic filed. They conduct...

College-level electrical engineering and computer science textbook highlighting the applications of continuum electromechanics.

Students learn the relationship between the electric and magnetic fields. Specifically, they verify that a magnetic field is created in a current carrying coil of wire and a changing magnetic field can induce a current in another coil of...

This lesson will show how a particle can travel in a wave form, by following perpendicular electric and magnetic fields. It is 1 of 4 in the series titled "Electromagnetic Waves."

This lab is designed to have students look at the deflection of a cathode ray beam using magnetic fields and electric fields.
