Demonstrate the classic “ice pail” experiment and show how charges distribute on a hollow conductor.
A Faraday cage illustrates that electric charge resides only on the outside surface of a hollow conducting object. When the cage is charged, like charges spread out to maximize their distance from one another, so the excess charge appears on
the exterior of the cage and no net charge is detected inside. Inserting a flask-form electroscope into the cage shows this effect clearly: the electroscope leaves remain at rest even when charge is applied to the outside of the cage.
The molded plastic cage is 10.5 in tall and 4.5 in wide and mounts on an insulating stand for stable setup. Insulating stand, charging rod and activity guide are also included to support classroom demonstrations and guided investigations. Required but not included are electrostatic materials and a standard flask-form electroscope. Includes activity guide.
