John Ambrose Fleming was an electronics pioneer who invented the oscillation valve, or vacuum tube, a device that would help make radios, televisions, telephones and even early electronic computers possible. A brilliant innovator,...

Enrico Fermi was a titan of twentieth-century physics. He outlined the statistical laws that govern the behavior of particles that abide by the Pauli exclusion principle and developed a theoretical model of the atom in his mid-twenties....

Siegmund Loewe was a German engineer and businessman that developed vacuum tube forerunners of the modern integrated circuit. He pioneered both radio and television broadcasting, and the company he established with his brother, David...

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

English chemist Sir William Crookes (1832 - 1919) invented the Crookes tube to study gases, which fascinated him. His work also paved the way for the revolutionary discovery of the electron and the invention of X-ray machines.

For a man whose career involved the entire known universe, John Kraus had a remarkably insular upbringing. He was born and raised in Ann Arbor, Michigan, and earned his bachelor's, master's and doctoral degrees in physics, all at the...

Like resistance, reactance slows an electrical current down. Explained by Lenz's Law, this phenomenon occurs only in AC circuits. (Java tutorial)

John Bardeen was one of a handful of individuals awarded the Nobel Prize twice and the first scientist to win dual awards in physics. Both times, he shared the prize with others. The first time his co-recipients were Walter Brattain and...

A collection of video lectures from a course that explores the application of electrical engineering topics. Webpage includes twenty-eight lectures from a professor at the University of California, Berkeley. Lectures vary in length and...

This site provides links to a variety of government-sponsored overviews and articles on electromagnetic fields and their associated health risks.

College-level textbook highlighting the interaction of electromagnetic fields with media in motion. Types of electromechanical interactions discussed include rotating machinery, plasma dynamics, the electromechanics of biological...

You will learn about a voltaic battery and to see if it's powerful enough to light up a light bulb

In this activity, students make a battery using different fruits and vegetables, a copper penny, and a zinc washer. They use a voltage probe to collect data on voltage and compare the values of different batteries.

This article discusses the properties of electromagnetic radiation and photons.

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.

This very simple, but effective generator shows in a wonderfully engaging way the fundamentals of electricity generation. The generator is made from a coil of wire wound around the outside of a plastic 35mm-film can. The two coil ends...

In this experiment, students experience the Curie point--and what happens when a piece of iron gets too hot to attract a magnet.

[Free Registration/Login may be required to access all resource tools.] Covers the discovery of electromagnetism, how it relates to electricity, and Faraday's law.

[Free Registration/Login Required] In this lesson students learn the parts of a circuit, build series and parallel circuits, learn about insulators and conductors, and more in this interactive multimedia flipchart.

An electromagnetic induction model that simulates an electric generator made from a conducting loop rotating in a uniform magnetic field and connected to an ammeter.

Spanish-language site lets students discover the life and work of this physicist and engineer, who is known for his studies of electric charges.

Read about all the different kinds of potential and kinetic energy. Includes energy formulas and examples of energy applications.

The Discovery Channel provides numerous topics that are the most popular science topics taught in upper elementary and middle school. Content is organized by topics (Bacteria, Oceans, Solar System, etc.); all topics include quick facts,...

Students can use these simulations to understand concepts in electromagnetism. Simulations are available on the following concepts: Lorentz Force, The Hall Effect, capacitor, conductor, transistor, cyclotron, static electricity....
