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...

This site presents a procedure for creating your own electromagnet using an iron nail, some wire, and a battery. The site illustrates a connection between electricity and magnetism.

Fire lighted the night for many centuries. Then came Sir Humphry Davy and the birth of the arc lamp, an invention built upon in the years that followed by many.

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.

To understand a bubble chamber, picture the long, white streak an airplane leaves in its wake. That's water vapor produced by condensation from the plane's hot exhaust. Until the water particles evaporate, you can follow the streak to...

A cyclotron is a machine that allows scientists to shoot particle beams at other particle beams. The result of doing this is a spectacular smash up - but that's not why scientists do it.

As more and more American households acquired telephones, the pressure was on to create a better cable to accommodate the increasing demand. Engineers Lloyd Espenschied and Herman Affel answered the call.

Two years after Englishman John Ambrose Fleming invented a two-electrode vacuum tube, American inventor Lee De Forest one-upped him by developing a tube with three electrodes.

Acoustics, variable resistance and allegations of foul play contribute to the exciting story of the invention of the telephone.

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.

This lab was designed to have students test the factors that determine how much current is induced in a circuit when area of the circuit is changed. This lab is a quantitive lab that supplements the lab on magnetic flux.

This simulation demonstrates a rotating conducting disk in a magnetic field which produces a current or a self-exciting dynamo.

Simulate the movement of a rail gun in this interactive model. Learn how a magnetic field is generated by running electrical current through long rods that accelerates a current-carrying cross-rod.
