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...

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

Gerd Binnig co-developed the scanning tunneling microscope (STM) with Heinrich Rohrer. The STM allowed scientists entry into the atomic world in a new way and was a major advance in the field of nanotechnology. For their achievement,...

From ABC News in Science, Julie Steenhuysen's article covers research into antiferromagnets (or antimagnets) and their "external magnetic field."

Did you know that a piece of iron can lose its magnetism if heated too high? There is a point called the Curie point when iron is heated to a high enough temperature that its iron atoms are scrambled and can't line up to form a magnetic...

Change the size and orientation of a conducting loop falling out of a region of uniform magnetic field. Then, the data is plotted on an interactive graph.

Create a simple device to see how a force is exerted on a current by a magnetic field. This activity shows how an electric motor can be made with this force.

Scientists use image furnaces to grow crystals at very high temperatures. A built-in camera allows them to observe in action a delicate process that is equal parts art and science.

Complete this model of a Faraday loop by adding the equations to explicate a conducting loop in a constant magnetic filed.

"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.

Discusses some history of magnets, the science of magnetism, and interesting facts about them.

Learn the convention for describing the direction of magnetic fields. Challenge questions are included.

This site describes how to make several toys with magnets. It also gives an explanation of how they work and where to get the right kind of magnets.

Iron filings are used in this picture to show the path of magnetic field lines created by a magnet.

[Free Registration/Login may be required to access all resource tools.] Covers what electromagnetic induction is, how it occurs, the current produced from it, and how it is used.

A NASA space scientist provides 98 questions and answers about the sun, the center of our solar system.

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.

This simulation demonstrates a rotating conducting disk in a magnetic field which produces a current or a self-exciting dynamo.

This article helps explain the concept of electromagnetism as well as magnetic fields and the properties of the speed of light.

Luigi Galvani was a pioneer in the field of electrophysiology, the branch of science concerned with electrical phenomena in the body. His experiments with dissected frogs and electrical charges led him to suggest the existence of a...

Humphry Davy was a pioneer in the field of electrochemistry who used electrolysis to isolate many elements from the compounds in which they occur naturally. Electrolysis is the process by which an electrolyte is altered or decomposed via...

Heike Kamerlingh Onnes was a Dutch physicist who first observed the phenomenon of superconductivity while carrying out pioneering work in the field of cryogenics. An important step on the way to this discovery was his success in...
