Apart from the piezo generator, all of these generators are based on the same simple design, where magnets are rotated near to coils of wire (Faraday Induction). There is no coil switching so these are AC generators. On magnet movement,...

This tutorial reviews over electrical energy.

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...

Investigate Faraday's law and how a changing magnetic flux can produce a flow of electricity!

This site from Georgia State University Physics Department defines and explains the concept of potential energy. Using equations and graphics to illustrate the idea, it discusses the many types of potential energy (gravitational,...

In this What's Up in the Environment? video segment, an electrical engineer in Virginia and his 13-year-old son explain how they produce electricity in their home. [3:58]

A really fine and complete biography, quite lengthy. Some emphasis placed on his time at Princeton. A great deal of detail can be found here. Link here to the Joseph Henry House.

This site from the Human Genome Project provides a large collection of facts and information, demonstrations, experiments and project ideas. Written for teachers but easily adaptable for any type of student work. A good site to check out...

Here you can find what you need to scientifically assess battery performance. In this exercise (that should take about one week) learn how batteries work, how they wear out and most importantly, how to make valid measurements to assess...

Batteries are expensive to purchase in a store, but you can make one your self for exactly 24 cents. In this experiment, you will make your own voltaic pile using pennies and nickels and determine how many coins in a pile will make the...

At this site read about Ernest Rutherford (1871-1937 CE), the scientist who was awarded the Nobel Prize in Chemistry, "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances." This...

Through labs, readings, videos, and discussions, students learn about the concepts of Electromagnetic Induction.

Shake N' Light flashlights have been advertised on televisions across the nation in the recent year. But many do not understand just how they get energy to light up the bulb without using batteries. Do this experiment to make your own...

The World Health Organization probes into the feared associations between electromagnetic fields (EMFs) and cancer. Check out "What is EMF?" for detailed summaries on what electromagnetic fields are and the possible health effects, or...

Electrical currents and voltage are defined and illustrated.

Here's a whole different look at Faraday. His religion, Sandemanian, greatly influenced both his life and his science. This article looks deeply at that aspect of his life.

Build your own windmill and see how the wind can be converted into energy to produce electricity. This science fair project should help you understand the use of wind as a source of alternative energy. The Science Buddies project ideas...

Text and animated graphic show how lightning is an example of a natural capacitor.

Students face a game-like challenge to use electrostatic forces to move a charged puck into a goal. By placing charges on the rink, a charged puck can be attracted and repelled around obstacles and into a goal.

[Free Registration/Login may be required to access all resource tools.] Provides the definition of an electromagnetic wave, electromagnetic radiation, and electric and magnetic fields. Also discusses how electromagnetic waves begin,...

A large complete authoritative biography of Coulomb. Five large pictures, over a dozen links to contemporaries, references, a poster, other mathematicians. A fine source.

This lesson introduces students to the role of electricity and magnetism as they build a speaker. In addition, students explore properties of magnets, create an electromagnet, and determine the direction of a magnetic filed. They conduct...

This lesson will show how a particle can travel in a wave form, by following perpendicular electric and magnetic fields. It is 1 of 4 in the series titled "Electromagnetic Waves."

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