This is a sample lesson on electromagnetism. It includes animated diagrams, interactive exercises, an audio option for reading the text, and comprehension questions throughout where students can type their answers or pick from...

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...

Explore the world of vectors, by finding answers to questions like what are vectors, what are scalars, what is the difference between scalar and vectors, the magnitude of a vector, operations on vectors, and properties of a vector.

This lesson will show how a particle can travel in a wave form, by following perpendicular electric and magnetic fields. It is 2 of 4 in the series titled "Electromagnetic Waves."

A concise biography on Joseph Henry gives details on his education; his experimental work in chemistry, electricity, and magnetism; and the many board positions he held throughout his life.

An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln...

[Free Registration/Login may be required to access all resource tools.] Provides the definition of an electromagnetic wave, electromagnetic radiation, and electric and magnetic fields. Also discusses how electromagnetic waves begin,...

Contains brief biographical information on Michael Faraday, as well as the text of the following lectures delivered by Faraday: The Force of Gravitation, Gravitation-Cohesion, Cohesion-Chemical Affinity, Chemical Affinity-Heat,...

French physician Guillaume Benjamin Amand Duchenne invented a device that electrically stimulates muscles. The apparatus gave him new insight into neuromuscular disorders, earned him the epitaph of "father of electrotherapeutics," and...

The invention of the light bulb quickly created the need to track people's electricity usage. In 1872, Samuel Gardiner built the first simple power meter: a lamp with an attached clock that recorded the time the light was on.

The Earth, the moon, the stars and just about everything in between has a magnetic field, and scientists use magnetometers when they need to know the strength of those fields.

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

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.

A teacher unit which includes several hands-on activities about types of magnets, magnetism, and electrostatics. An activity designed to suit all grade levels. Many parts of the activity would be easily adaptable as a student project.

Simple line graph showing the inverse relationship between the amount of electrical resistance and the amount of work possible.

This activity will have students creating their own speaker with a paper cup, coil of wire, and magnet. The speaker operates by changing electric current into sound.

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

Text and animated graphic show how lightning is an example of a natural capacitor.

Students face a game-like challenge to use electrostatic forces to move a charged puck into a goal. By placing charges on the rink, a charged puck can be attracted and repelled around obstacles and into a goal.

This lesson helps students to understand the difference between magenets and electromagnets. They will also create an electromagnet.

This site from Cornell University provides a very short, very telling comparison of matter and charge. This is a good site to check out on the subject, with a chart diagram to help with further information.

Easy-to-read information and an illustration of an "electromagnet," a type of magnet in which the magnetic field is induced by the flow of an electric current.
