Make your unit on magnetism a force to be reckoned with! Physical science scholars examine the direction of force on charged objects through a simple interactive. Pupils control the charge of the stationary object, then observe how it...

Here are two electromagnetism homework assignments rolled into one. The first eight practice problems deal with the magnetic field and magnetic force exerted by current-carrying wires. The second set of seven problems are specific to...

After high schoolers have learned about electromagnetic induction, they can solve these 10 practice problems. They calculate magnetic field strength, magnetic force, electromotive force, and output voltage. This is a choice option as a...

In this magnetism instructional activity, students review what magnetism is by matching 5 words to their definitions. Then students use a diagram showing the pattern of iron fillings around magnets to complete 4 short answer questions.

A clear explanation of Newton's First Law of Motion, the law of inertia, with diagrams and real-world examples. Useful for both students and teachers. Written by a high school physics teacher.

This site is a description of the earth's magnetic field, including a section on the "Dynamo effect," a proposed explanation for the origin of the earth's magnetic field.
