In the modern world, virtually everyone is familiar with electricity as an accessible, essential form of energy. In electricity's earlier days, scientists used the buildup and release of static electricity.

The Scottish instrument maker and inventor James Watt had a tremendous impact on the shape of modern society. His improvements to the steam engine were a significant factor in the Industrial Revolution, and when the Watt engine was...

Awarded more than 100 patents over the course of his lifetime, Nikola Tesla was a man of considerable genius and vision. He was reportedly born at exactly midnight during an electrical storm, an intriguing beginning for a man who would...

In the 17th century, German scientist Otto von Guericke built and carried out experiments with a sulfur globe that produced static electricity.

Physicist Felix Bloch developed a non-destructive technique for precisely observing and measuring the magnetic properties of nuclear particles. He called his technique "nuclear induction," but nuclear magnetic resonance (NMR) soon became...

Most of us have seen the rainbow-hued breakdown of the composition of light. Light is of course a form of energy. A magnetic field changes the behavior of light- a phenomenon known as the Zeeman effect.

Has anyone ever told you that you have a magnetic personality? Have you ever heard that opposites attract? These common phrases are both based on the properties of magnets and magnetic electricity. In this science fair project, learn how...

Molecular Expressions is a comprehensive scientific educational resource that features a considerable collection of interactive Java tutorials relating to electricity and magnetism. Tutorials range in complexity and difficulty of...

This is a Java tutorial showing the simple voltaic (or galvanic) electrical cell, which is the most basic type of "wet" cell and demonstrates the fundamental chemistry behind batteries.

CollegeBoard offers a page of resources for students and teachers of AP Physics C: Electricity and Magnetism. Find course and exam information, teaching resources, articles, and recommended links.

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

When electricity became available to the masses, utilities needed meters to record customer usage. This early 20th century model resembles many in use today. (Java tutorial)

Magnetic shunts are often used to adjust the amount of flux in the magnetic circuits found in most electrical motors. (Java tutorial)

Electricity goes through some ups and downs on its way from the power plant to your house. See how it works in this interactive activity.

This tutorial illustrates how the flow of water through a system of pipes can be used to understand the flow of current through an electric circuit.

Electric motors turn electricity into motion by exploiting electromagnetic induction.

This circuit is most commonly used to determine the value of an unknown resistance to an electrical current.

The MagLab's bus tunnel has an aluminum track, but it doesn't carry passengers: it carries electricity, up to 56 megawatts of it.

A capacitor is similar to a battery in that both store electrical energy. But a capacitor can't actually produce new electrons; it only stores them.

English mathematician Peter Barlow devised an instrument in 1822 that built on advances from earlier in the century (including the invention the battery) to create a very early kind of electric motor.

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

A module that uses pictures, videos, reading passages, and review question to go over what a magnet and magnetic pole are, and how magnetic force is related to magnetic field. This site may require free registration to access all...

Electricity is the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which...

Explore what an electric field is and how electric fields interact with this module. Module includes a video, interactive activity, and review questions.
