Faraday Cage 5B20.30


Faraday cage, electrometer, and cables located in Electrostatics Cabinet, B1.

Charge producers (rods and fur) located in Electrostatics Cabinet, A1.

Hot air gun located in Thermodynamics Cabinet, B2

Connect the electrometer to the cage, with ground going to the outside cage.

Charge one of the rods by rubbing it with the fur.

This series of experiments illustrates something of the nature of electrostatic potential:

Each of the cages is an equipotential, and the inside cage is shielded from fluctuations in potential that occur outside the outside cage.

The rods may be neutralized by passing hot air over them, using the hot air setting of the hot air gun.

Many other experiments are possible.
