Compares paramagnetism to diamagnetism and lists the elements that are diamagnetic and paramagnetic.

This lesson helps students to understand the difference between magenets and electromagnets. They will also create an electromagnet.

Students design and construct an electromagnet that must pick up 10 staples. They begin with only minimal guidance, and after the basic concept is understood, are informed of the properties that affect the strength of that magnet. They...

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...

In this activity, students use the same method as in the activity from lesson 2 to explore the magnetism due to electric current instead of a permanent magnet. Students use a compass and circuit to trace the magnetic field lines induced...

Through labs, readings, videos, and discussions, students learn about the concepts of Electromagnetic Induction.

Hans Christian Orsted's accidental discovery that an electrical current moves a compass needle rocks the scientific world; a spate of experiments follows, immediately leading to the first electromagnet and electric motor.

How are magnetism and electricity related? Students will explore the relationship between magnetism and electricity, learn how to construct an electromagnet, and discover everyday uses of electromagnets. Students will create a multimedia...

Students learn more about magnetism, and how magnetism and electricity are related in electromagnets. They learn the fundamentals about how simple electric motors and electromagnets work. Students also learn about hybrid...

James Clerk Maxwell was one of the most influential scientists of the nineteenth century. His theoretical work on electromagnetism and light largely determined the direction that physics would take in the early twentieth century. Indeed,...

[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.

Research resources for James Maxwell (1831-1879), who did revolutionary work on electricity and magnetism and on the kinetic theory of gases.

College-level electrical engineering textbook starting from the Coulomb-Lorentz force law on a point charge. Sample problems that reinforce the content are found at the end of each chapter. Includes downloadable excerpts of the textbook...

A discovery by Hans Christian Orsted forever changed the way scientists think about electricity and magnetism. While preparing to perform an experiment during a lecture at the University of Copenhagen, he found that the magnetized needle...

Charles-Augustin de Coulomb invented a device, dubbed the torsion balance, that allowed him to measure very small charges and experimentally estimate the force of attraction or repulsion between two charged bodies. The data he obtained...

Although he was not the first person to observe a connection between electricity and magnetism, Andre-Marie Ampere was the first scientist to attempt to theoretically explain and mathematically describe the phenomenon. His contributions...

American inventor Lee De Forest was a pioneer of radio and motion pictures. He received more than 300 patents over the course of his lifetime, the most important of which was for a three-electrode vacuum tube, or triode, that he called...

The discovery of radio waves, which was widely seen as confirmation of James Clerk Maxwell's electromagnetic theory and paved the way for numerous advances in communication technology, was made by German physicist Heinrich Hertz. In the...

This article surveys inductance and its different forms. It discusses numerous topics associated with inductance such as Faraday's Law, self and mutual inductance, inductors, and magnetic field lines.

Students use a simple set up consisting of a coil of wire and a magnet to visualize induced EMF. First, students move a coil of wire near a magnet and observe the voltage that results. They then experiment with moving the wire, magnet,...

Einstein Light highlights the Theory of Special Relativity and related topics. Learn how Galileo, Maxwell, and Einstein contributed to our knowledge of relativity, electricity, magnetism, and time by watching fun, interactive modules.

This site from The Florida State University provides an informational page on electromagnetic radiation discusses the characteristics and properties of its many forms including X-rays, gamma rays, ultraviolet radiation, infrared...

This site presents a procedure for creating your own electromagnet using an iron nail, some wire, and a battery. The site illustrates a connection between electricity and magnetism.

A collection of video lectures from a fundamentals of physics course taught at Massachusetts Institute of Technology. The course is the second in the sequence and focuses on electricity and magnetism The videos feature topics on...
