Learn about Andre Marie Ampere, one of the founders of the science of classical electromagnetism, which he referred to as electrodynamics.

[Free Registration/Login Required] Explore the concept of Morse Code and how signals are transferred over great distances by using telegraph machines based on electromagnets using our interactive simulation. A PDF worksheet and a video...

[Free Registration/Login Required] Students will learn the different components of the Electromagnetic Spectrum. They will learn why these different waves are useful in our every day life. They will also learn the difference between a...

[Free Registration/Login Required] This flipchart introduces fifth grade students to the electromagnetic spectrum and focuses on the visible light spectrum, but all types of energy waves in the electromagnetic spectrum are touched on. It...

This page defines electromagnetic radiation. Included are links to more information.

Ultraviolet (UV) light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects can see them. The specific wavelength values are given. Uses and applications of these waves are explained.

This site from Cornell University provides a very short, very telling comparison of matter and charge. This is a good site to check out on the subject, with a chart diagram to help with further information.

Manually or computer generated, students can test radio waves being transmitted from a virtual radio station to a home. Study the curve, vectors, electric field, and more.

This lesson plan contains several activities designed to help the student understand the magnetic effects of an electrical current.

Read and fill in the blanks of this passage explaining atomic history. Each blank has a dropdown menu with choices. When you finish, click CHECK MY ANSWERS. If you pick a wrong answer, the right answer will be displayed along with your...

A good explanation of what the property of magnetism is and how it occurs naturally in lodestone and can be generated in metals such as steel. It describes how a ferromagnetic material such as iron becomes magnetized when near a...

Part of an anecdotal history on optics and the study of light. Extremely thorough treatment of the scientific evidence which led scientists to believe in the particle nature of light. Includes a short biographical sketch and discusses...

This lesson explains how a DC electric motor works including a diagram and description and links to a video and a test.

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...

In this physical science lab, students will investigate ways to control an electromagnet, how adding coils of wire can change the magnet, and the differences between an electromagnet and a bar magnet. Students will explain in their...

College-level physics course highlighting electricity and magnetism. This course is divided into several modules including electric fields, magnetic fields, electromagnetic forces, conductors and dielectrics, electromagnetic waves, and...

Students will investigate the properties of light waves. They will learn about the different types of electromagnetic waves and mechanical waves, and investigate the phenomena of reflection, refraction, interference, and diffraction.

Students explore electromagnetism and engineering concepts using optimization techniques to design an efficient magnetic launcher. Groups start by algebraically solving the equations of motion for the velocity at the time when a...

This illustrated essay from A Science Odyssey Web site explains the science behind radio waves, including the role of electrons and electromagnetic fields.

[Free Registration/Login Required] Are there colors we don't see? This simulation addresses that question by exploring light as an electromagnetic wave. Learn how the electromagnetic wave relates its wavelength and frequency to the...

Light is an example of an electromagnetic wave. Electromagnetic waves can travel through the vacuum of interstellar space. They do not depend on an external medium-unlike a mechanical wave such as a sound wave which must travel through...

Through an introduction to the design of lighting systems and the electromagnetic spectrum, students learn about the concept of daylighting as well as two types of light bulbs (lamps) often used in energy-efficient lighting design....
