Alternating current behaves differently, depending on what components are in a circuit.

Just a year after electromagnetism was discovered, the great scientific thinker Michael Faraday figured out how to turn it into motion. (Java tutorial)

An experiment to find out how an old-style doorbell works.

Two scientists share the credit for discovering, and then interpreting, the phenomenon of electromagnetism.

For this interactive activity, students will explore electricity and be able to design and create a complete electrical circuit. Students will also learn what is necessary to light a light bulb. Creative thought, ideas, and,...

Can you hear a magnet? In this activity you will be able to transfer the sound from your iPhone, iPod or radio to a cassette-tape player.

See drawing from Hans Christian Orsted's lab notebook showing an experiment in which an electric charge passing through a wire seemed to create a magnetic field!

Investigate with a bar magnet and coils to learn about Faraday's law. You can also play with electromagnets, generators, and transformers!

This set of activities has students using everyday items (batteries, magnets, compasses, iron and paper clips) to reveal the connection between electricity and magnetism. Ideally, students will already have experience building simple...

This lesson discusses the result of a charge being subject to both electric and magnetic fields at the same time. It covers the Hall effect, velocity selector, and the charge to mass ratio. Given several sample problems, students learn...

This site provides a list of the topics and links to the Physics (Combined Science)courses offered in GCSE Bitesize and a list of contents of each. The topics include the following: Energy, Electricity, Matter, Radioactivity, Forces,...

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....

Here is a project that is almost like a magic trick: with a strong magnet and a simple apparatus you can build yourself, you can make a coin "walk" up and down a wire coat hanger. This project is an interesting way to learn about the...

An interactive simulation that teaches about Faraday's Law, magnets, and magnetic fields by showing how a change in the magnetic flux can produce a flow of electricity. This simulation can either be downloaded or played online and...

This PBS site offers videos and activities are hands-on challenges that focus on the engineering design process. They use simple materials, allow for multiple solutions, and are ideal for ages 9-12.

Solar cells provide a clean way of making electricity directly from sunlight. In this project you will build a simple circuit and experimental setup to investigate whether the power output of a solar cell changes with ambient temperature.

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...

Explore the origin of energy bands in crystals of atoms. The structure of these bands determines how materials conduct electricity. Java required.

Read about the amazing development of plant-powered lamps that are bringing electricity to a village in remote Peru. Includes video.

Students are given a history of electricity and its development into the modern age lifeline upon which we so depend. The methods of power generation are introduced, and further discussion of each technology's pros and cons follows.

NASA provides a nice blending of the achievements of three scientists, Oersted, Ampere, and Maxwell. This done by NASA-sponsored International Solar-Terrestrial Physics group. Lots of pictures, diagrams, and scientific explanation. Good...

In this quick activity, you will make a simple motor using nothing but a battery, magnet, and a piece of wire.

Computers evolve into PCs, researchers discover one new subatomic particle after another and the space age gives our psyches and science a new context.

The telephone and first practical incandescent light bulb are invented while the word "electron" enters the scientific lexicon.
