How Faraday Cages Work
Electricity is the lifeblood of many aspects of our world. Without volts and amps, many of our technological innovations would cease to exist. Even our bodies wouldn’t function without an electrical charge zipping through our cells. But what electricity gives, electricity can take away. Too much electricity can electrocute people. Likewise, it can kill our modern electronics and machines.
But thanks to Michael Faraday, the brilliant 19th-century scientist,* and one of his namesake inventions, the Faraday cage, we humans have developed plenty of ways to control electricity and make it safer for our computers, cars and other inventions — and for us, too.
Faraday cages shield their contents from static electric fields. An electric field is a force field surrounding a charged particle, such as an electron or proton.
