Product Details
Create power! Demonstrate the fundamental principles of generators by converting the spinning mechanical energy into electrical energy that will light an LED. In this simple, easy-to-make device, two powerful neodymium magnets spinning in a coil of wire induce a current, in accord with Faraday’s Law. You can also use the device to show students the difference between direct and alternating current. They will surely be impressed! Includes complete instructions and a reproducible student worksheet. Concepts: Electric generators, electromagnetism, alternating current, Faraday's law.
Materials Provided: Cardboard tube, iron nail, red LED, magnet copper wire, neodymium magnets, sandpaper.
