[Free Registration/Login may be required to access all resource tools.] What a solenoid is and how to change the strength of its magnetic field, and some uses of solenoids.

Step-by-step illustrated instructions show how to build a simple electric motor using everyday materials to make a wire coil spin. An explanation of the science involved is given at the end, as well as tips on troubleshooting any...

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

In this experiment, students experience the Curie point--and what happens when a piece of iron gets too hot to attract a magnet.

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...

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.

[Free Registration/Login Required] Understand how magnetic fields generated by solenoid coils can be used to create an operating doorbell using this interactive simulation. A PDF worksheet and a video tutorial are also available. [1:51]

Simulate the motion of a charged particle in electric and magnetic fields, and then complete the equations of motion using the Lorentz force law.

The home page of the The James Clerk Maxwell Foundation, a charitable foundation to commemorate the life and work of James Clerk Maxwell. View Maxwell's house and read about the personal life of this notable scientist.

[Free Registration/Login Required] Understand how the magnetic field generated by loops of current-carrying wire is used to create measuring devices like voltmeters and ammeters with this interactive simulation. A PDF worksheet and a...

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

[Free Registration/Login may be required to access all resource tools.] Explains what electromotive force, or EMF, is, and how to calculate the EMF of a moving wire in a magnetic field.

"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.

Students explore how various energy sources can be used to cause a turbine to rotate and then generate electricity with a magnet.

[Free Registration/Login Required] Use this interactive simulation to understand how magnetic forces applied to charges in motion generate circular [centripetal) motion, and how the paths these particles leave provide insight into their...

A short biography about Charles Coulomb, known for developing Coulomb's law, the definition of the electrostatic force of attraction and repulsion.

At this site from the Nobel e-Museum, you can read about the scientific work of Lord Rayleigh (1842-1919 CE). This article includes information on his education and experiments with light and sound waves.

Lenz's Law is defined and demonstrated with an interactive Java applet that shows the relationship between field lines of a magnetic and a conductor ring.

A teacher lesson plan which includes several student activities on magnetism, force fields, and magnetic induction. May provide an idea for a student project or lab investigation.

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...

Students are challenged to design a method for separating steel from aluminum based on magnetic properties as is frequently done in recycling operations. To complicate the challenge, the magnet used to separate the steel must be able to...

If you put on clothes that were washed in a washing machine, rode in a car, ate food from a fridge, warmed up lunch in a microwave, or played a video game, you used an electric motor. Try this science fair project and you'll learn how to...

A concise biography on Joseph Henry gives details on his education; his experimental work in chemistry, electricity, and magnetism; and the many board positions he held throughout his life.

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...
