An article defining what magnetic force is and how to calculate it.

A reference page to learn about magnetic flux means and how to calculate it. Reference page includes explanation and exercise.

Magnets can be used as toys, tools, and more. Identify how magnets work, what a magnetic field is, as well as what a magnetic force is.

[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.

Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.

A module that uses pictures, videos, reading passages, and review question to go over what a magnet and magnetic pole are, and how magnetic force is related to magnetic field. This site may require free registration to access all...

Do you know how to induce an electromotive force? This reference page will help you understand why Faraday's law mean and how to use it.

This lesson focuses on electric charges. Electric current is the flow of electric charge. Some insulating materials become electrically charged when they are rubbed together. A substance that gains electrons becomes negatively charged,...

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.

What is a magnet? In this activity, students will investigate magnets and what they attract. They will observe, explore, ask questions, predict outcomes, then discuss and record their findings.

This lesson will introduce what a magnet is and how magnets work.

[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.

Explore the chaotic motion of a pendulum that is swinging above several magnets that are fixed in place and see what patterns you can find.

Learn what a compass is, how it works, and how you can create a simple one using a sewing needle, magnet, bowl of water, and a piece of paper.

In this activity, students will design a process that removes the most iron from the cereal. This activity is meant for the students to experiment with different materials using what they know about iron, magnets, and forces to design...

Explore what an electric field is and how electric fields interact with this module. Module includes a video, interactive activity, and review questions.
