Additional Details

The link between electricity and magnetism finds its legendary roots back to Hans Christian Orsted when he supposedly found that electric current affected his compasses during a student lecture. That piece of scientific history may be one of exaggerated legend, but the marriage of electricity with magnetism has been widely known for over a century, later to be given a full mathematical explanation by Lord Kelvin and James Clerk Maxwell.

The concept of electron movement causing the production of an ensuing magnetic field is a fundamental model used in describing electromagnets, generators, transformers, and electric motors. Students can witness the magnetic fields produced by electron movement using compass deflections and observe first-hand the mechanical spin of a solenoid in an electric motor. Using the "Electricity & Magnetism Light Bulb Demo", you will demonstrate to your students the relationship between electricity and magnetism in an amazing and unconventional way, using a light bulb under conditions not normally observed in everyday life.

Notice: The bulb's filament is very fragile. When using the bulb in AC mode, we suggest holding a small neodymium magnet (P8-1123) about 1 inch above the top of the bulb for short periods of time. Placing a magnet closer than 1 inch to the AC current bulb could break the bulb's filament.

Please note: Neodymium magnet is required and not included.
