HyperPhysics is an exploration environment for concepts in physics by Georgia State University which employs concept maps and other linking strategies to facilitate smooth navigation. This section focuses on electricity and magnetism.

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...

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.

Our magnets are like world-class athletes - Team Tesla, if you will. They have an awful lot of power, but to stay in that kind of shape, they need to eat and drink - a lot.

Learn about magnets, magnetic forces, and how magnets make things move.

Students use iron filings to explore the magnetic field around a magnet and record their observations then apply their experience with the magnet to understand the magnetic field around Earth.

This is a straightforward project that shows you how data can be digitized and stored on magnetic recording media. You'll learn how alpha-numeric characters are digitized, and you'll use bar magnets to represent the individual data...

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...

The purpose, life, and hazards of the Earth's magnetic field are discussed as they relate to magnetic storms. This includes their impact on animals, auroras, and even compasses. Interactive features are also included in this...

Vasarosnamenyi Baro Eotvos Lorand, better known as Roland Eotvos or Lorand Eotvos throughout much of the world, was a Hungarian physicist who is most recognized for his extensive experimental work involving gravity, but who also made...

Svante Arrhenius was born in Vik, Sweden, and became the first native of that country to win the Nobel Prize. The award for chemistry was bestowed to him in honor of his theory of electrolytic dissociation. Arrhenius also developed the...

Robert Andrews Millikan was a prominent American physicist who made lasting contributions to both pure science and science education. He is particularly well known for his highly accurate determination of the charge of an electron via...

Ever wonder how a compass worked to point you to the Arctic? Explore the interactions between a compass and bar magnet, and then add the earth and find the surprising answer.

Theoretical physicist Richard Phillips Feynman greatly simplified the way in which the interactions of particles could be described through his introduction of the diagrams that now bear his name (Feynman diagrams) and was a co-recipient...

In this science fair project, use Google Earth to determine if large mammals align themselves in respect to the earth's magnetic field. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...

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.

It's hard enough to weigh something as itty bitty as atoms or molecules. Factor in that they're careening by faster than Jeff Gordon on steroids, and you get an idea what scientists are up against. Using comet particles from NASA's...

An overview of the history, applications and science of superconductivity, including the Meissner effect, BCS theory, Type 1 and Type 2 superconductors and high-temperature superconductivity.

Exploratorium Science Snacks are miniature science exhibits and experiments that can be made with common, inexpensive, easily available materials. These electricity snacks represent a set of devices that you can build and experiment with...

An article that discusses the coupling of an electric field with a magnetic field to create electromagnetic waves. Article also discusses how different types of electromagnetic waves have different wavelengths which forms the...

A high-level scientific explanation of the way the eye senses light and sees images and color. Excellent graphics help you visualize complex workings of the human eye.

This site discusses primary lighting sources and gives information on the different properties and spectral characteristics of each. Also includes links to some interactive Java applets.

An in-depth discussion on reflection of light can be found here. Among the topics discussed include are the difference between specular and diffuse reflection, concave and convex mirrors, facets, total internal reflection, and much more....
