What is a Faraday Cage and How Does it Work?

TLDR A Faraday cage is a conductor of electricity that surrounds an object to protect it from electrical charge or electromagnetic radiation. It acts as a shield, keeping electrostatic charges outside and preventing electromagnetic waves from entering or leaving, making it useful for protecting against shocks, interference with data, and the escape of sensitive information.

Timestamped Summary

00:00 Faraday cages are named after Michael Faraday and are essentially a type of cage that can protect against lightning strikes.
04:40 A Faraday cage is a conductor of electricity that surrounds something to protect it from electrical charge or electromagnetic radiation.
09:27 A teenage cork ball was used by Ben Franklin to demonstrate the concept of a Faraday cage, which Michael Faraday later investigated and confirmed by conducting his own experiments.
14:01 Michael Faraday took Ben Franklin's findings on electricity and explained that conductors, like a can, have loose electrons that can move and carry an electrical charge.
18:14 A Faraday cage acts as a shield that keeps an electrostatic charge outside and protects you from being shocked or electrocuted.
22:46 A Faraday cage acts as a shield that prevents an electrostatic charge from entering and also blocks electromagnetic waves from coming in or going out, depending on the material and size of the cage.
27:48 Faraday Cages can be used in science labs, hospitals, and even airplanes to protect against electromagnetic radiation and interference with data.
32:17 Faraday Cages can be used to protect against electromagnetic radiation, but they are not always perfect and may not block all wavelengths.
36:46 Faraday cages can also be used to prevent electromagnetic radiation from escaping, which can be useful for protecting sensitive information and equipment.
41:36 Faraday cages can also be used to prevent electromagnetic radiation from escaping, which can be useful for protecting sensitive information and equipment.
45:52 Eels travel thousands of miles to different locations throughout their life, and people used to think they were different species at different stages, but they are actually the same eels.
