video - Vibrating Lamp Filament
Purpose:To demonstrate the Lorentz force on the moving electrical charges.
Plug a bulb with a STRAIGHT filament into AC supply. Bring a magnet to the bulb and watch the filament vibrate.
For contrast plug it into a DC source to see the difference.
Hints:Do not use too strong of a magnet or a bulb above 60W. It'll break the filament.
