Faraday Cage (5B20.30)

Description:

A large mesh wire cage fits over the electroscope, shielding it from outside electric fields. A high voltage source (a charged acrylic rod) brought near the cage will not deflect the electroscope.

Procedure or Operation Notes:

1) Bring a charged acrylic rod near (but not touching) the electroscope. The electroscope leaf will be deflected as the rod is brought closer to the top terminal.

2) Place the wire mesh Faraday Cage over the electroscope making sure that it makes good contact with the metal sheet.

3) Again, bring a charged acrylic rod close to the electroscope but this time the electroscope will not be affected.
