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.

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

Explains electrical resistance and how it is measured using the formula for Ohm's Law.

In 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, brainstorming...

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

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

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...

Students teams each use a bar magnet, sheet of paper and iron shavings to reveal the field lines as they travel around a magnet. They repeat the activity with an electromagnet made by wrapping thin wire around a nail and connecting...

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....

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...

Use your knowledge of physics concepts like electricity, reflection, magnetism, etc. to complete interactive online puzzles.

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.

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.

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...

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.

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

A simulation of the Rutherford experiment. Includes an animation and an explanation of the history behind the experiment.

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.

[Free Registration/Login Required] An informational text about how a compass works using electromagnetic force. A question sheet is available to help students build skills in reading comprehension.

"A magnet exerts a force on current-carrying wire." This simple device shows how magnets affect wires with current in them, the basis of the electric motor. If you see, feel and understand this, the electric motor becomes very clear.

Investigate a the forces exerted on a charged particle by electric and magnetic fields. Initially, find out how the charge behaves in an electric field. Then, see how the charge behaves in a magnetic field. Finally, initiate both fields...
