Electrical engineers entertain and explain how to construct an electromagnet-driven motor. Kellie and Mike, the hosts of the show, are enthusiastic teachers that will help introduce a project that you likely include in your middle school...

The compass was first used in 206 B.C., but we didn't discover magnetic poles until 1263 A.D. Presentation begins with the history of magnetism before continuing on to magnetic fields, magnetic forces, electromagnets, currents,...

Introduce your class to the idea of magnetic fields around electrical wires with an activity that provides the information about the direction of a magnetic field around a wire carrying an electric current.

I don't get electricity jokes, watts so funny about them? The 13th in a series of presentations covers energy, motors, currents, generating electricity, calculating electrical energy cost, transformers, and batteries.

Steel is a man-made alloy or a mixture of metals. Lesson 18 in this series of 36 focuses on metals and their extraction from Earth. Individuals read about, discuss, and answer questions after learning how people find most metals, the...

Round and round it goes. Class members observe a current carrying loop in a magnetic field and calculate its associated torque. They then apply what they have learned to example problems to solve for the torque and to calculate the...
