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. Time Required: 15 minutes Materials Provided: Cardboard tube, iron nail, red LED, magnet wire, neodymium magnets, sandpaper. Note: Also available as a Classroom Set with enough materials for eight student groups.

Performance Expectations

MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces
MS-PS2-5. Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact
HS-PS2-5. Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.
