    That Faraday cage explanation was bogus. A car is a Faraday cage too, yet you can still place calls while you're in a car. -__-

    i thought she was going to turn the microwave om

    Microwaves is ionizing radiation cause you can create plasma inside a microwaveoven can see many expiraments about this.

    Wait wait wait. Faraday cages keep external electric fields from entering the cage, but they don't work the other way around. If you have a source of an electric field inside the cage, that electric field will exit the cage. A simple application of Gauss's Law to a charged particle inside a sphere confirms this. A metal barrier will attenuate the field exiting the cage, but it wouldn't cancel it out completely like it would an external field.

    Here is a clear explanation of the effect that I found informative. Hope it helps anyone that still struggles with the gaps in Faraday Cage explanations.

    hey physics how much does phone radiation affect our brain's electric field?

    I know that there are resonant lengths for antennas at which they are most efficient. For example, a 1/4 wavelength antenna is more efficient than a slightly longer one, but a full wavelength antenna is even more efficient. Can Faraday cages have these same sort of "nodes" around which signals can pass through? I would expect that, even though a small amount of leakage occurred, the attenuation would be far too great for the 2.4 Ghz Wi-Fi signal to get through unless there was something else going on. The FCC maximum allowed transmit power for 2.4 Ghz Wi-Fi is 1 watt but it's not uncommon for microwaves to radiate 500-1,000 watts. You didn't give the power level detected, but it looked to be faint at whatever scale you were measuring.

    This is why your IT Guy doesn't like your microwave.

    Older microwaves stopped wifi

    We recently got a new microwave an my internet just dies whenever it turns on

    2:05 so what's the point of, "is microwave radiation getting out of my microwave?" It's getting in your food! What's the point!?
