Code Number: 5B20.50
Demo Title: Electric Field Lines and Flux
Procedure:
See also 5G20.74 in Electricity and Magnetism.
Set up the Flux unit as shown. Make sure to tighten the leg set screws securely. Place the surround box around the unit if using the fog machine or fog from the can. Chose the desired size white board which can then be place flat or at any angle in the box to cut as few or as many of the field lines as needed.
