Faraday Cage Protects from 100,000 V :: Physikshow Uni Bonn

[68Mannheim259]

dürfte nix passieren wenn die drinnen sitzende person den käfig von innen anfässt oder? die Ladung sitzt ja an der außenseite des käfigs?!

[CuriousVulcan]

How do you build a Home Built Faraday Cage to go against H.a.a.r.p. frequencys

[Cengiz78x]

The people of earth are grateful to these stupid gayrmans for re-discovering America LOL

[08Kutt]

hahah i have a 1,5 million volts lightning simulator, 1,5 meters of thick lightnings!

yeah, but how many amps? it's the amps that kill

[superkeesmen]

awesome

@magalie1157

you can block an infrared ray with a thick piece of wood, that is why remote controls for TVs don't always work when the table is in the way. other parts of the EM spectrum, like Gamma Rays, would need several inches of dense lead to stop them. This video is about the nullification of the internal electric field inside the cage. Not related to EM radiation really, but built right, a cage would withstand a large EMP pulse. But it would not stop any form of radiation.

@magalie1157

this is electricity in the video, not other kinds like microwave. There is more info online about emf radiation and how to use materials to make shielded rooms, faraday cage, etc. I have seen woven fabrics made of copper, silver, etc and they are not wire, which has larger holes in the mesh. The fabrics have a fine weave. Use grounding devices (3 prong plugs), attach to conductive fabrics with clips, then plug in. Also use solid sheets of metal, aluminum plate, on walls, etc.

0:02 Did she just say "fa sheezy"?! Keak Da Sneak would be proud! :-)

[RNumbers]

Sure. Either that or "verschliessen."

[redtails]

That's an amazingly educational class, if you think about it

[boxa888]

put up a small scale model of teslas wireless energy system! please check it out! i put up alot of info so that we can learn how it works and bring it back! his system is needed now before its too late! wireless power and freedom for everyone! its all on my youtube!

[redtails]

If I remember correctly Tesla's wireless power only works when the frequency resonates along the transmitter and receiver, at an efficiency of around 60% over a couple of metres. If the frequency isn't exactly right and the distance too long the efficiency falls back to far below 0.1%

[venomx2]

@redtails Your thinking of a Tesla coil, Boxa888 is probably talking about Tesla's amplifying transmitter.

[joesub007]

Now you can surf the internet after a nuclear bomb goes off because your computer won't be fried if you put it in a Faraday cage. Of course you have to take care that you're not fried.

[abbad0n]

also, the faraday box is used when some organizations steal expensive cars. they put them in a faraday cage to prevent gps localization or that kind of stuff until they find the device and deactivate it or destroy it

[AfterKnightShine]

It's totally safe inside..

[Doggieman1111]

they didn't show the part where the guy inside crapped his pants

[ibcnunabit]

A Faraday cage can be made of wire mesh or perforated/solid metal which is grounded. It works by totally dissipating any electrical field applied to it. It's only limited by the amount of electricity that the wires in the mesh are capable of conducting.

This is really why your car is the safest place if you're out in an electrical storm. (Nothing to do with rubber tires; that's a myth.) Your car acts roughly as a Faraday cage, despite the windows creating large openings in it.

[highwayhokie]

@ibcnunabi......so the tires do conduct electricty? Even if it is not raining and there is a freak bolt of lightning?

[freedomchaser2402]

@highwayhokie no rubber doesnt conduct electricity. but a lightning bolt will have no problem jumping from the metal of the car to the ground...considering that it just jumped from the cloud to car

[debunker1905]

Is there a limit of voltage for a Faraday Cage?

I mean, is there a change that in an extremely high voltage, the eletric current hits the person inside it? The person doesn't need to touch anywhere in the cage, the eletric current simply beats the air resistance like a lightning in the sky and hits the person, can this happen?

[arizonapg]

well if the voltage is more than the material it's made of can handle then i guess so, otherwise electricity will take the path of least resistance to the ground and metal is a much better conductor than air or human.

[abbad0n]

the electricity always will find the shortest way in the most conductive material, so, i think it cant hit a person cuz we are not "that" good conducting electricity.

[kaaitj]

@debunker1905 No it can't as far as I know. When you energize the cage, the whole cage has the same potential, there will be no potential difference between the sides of the cage. So all the electricity will stay on the outside of the cage and there's no charge on the inside.

[febris1936]

sorry... i cant understand german so, watching the video, i dont really understand the Faraday effect. What are those red pieces? What are they made of?

And why it is said that the cage protects the man inside?

(sorry about my ignorance! :S )

[gigner2]

lol

[theCosmicQueen]

@givebeesachance

no those red strips are what happened when they took apart your brain, that's why you don't make sense.

[gigner2]

Read ibcnunabits comment, three above , its pretty much all correct

[ferdem01]

it doesn't look faraday cage at all, faraday cage is a totally closed structure and shields enclosed staff against to electromagnetic waves(actually electric field).

[Aidy89]

learn something about fysics k

[ferdem01]

There is no relation between this and faraday cage. First of all faraday cage is not a shield against to voltage. It is designed to provide shielding agains to electric field. Actually, electric field component of an electromagnetic wave. It must have certain thickness and it must not have holes being larger than incident electormagnetic wave's wavelength on its surface. These are the most important features of a faraday cage.

Research about what faraday really did my dear friend.

[wdelgenio]

A Faraday cage or Faraday shield is an enclosure formed by conducting material, or by a mesh of such material. Such an enclosure blocks out external static electrical fields. Faraday cages are named after physicist Michael Faraday, who built one in 1836.[1]

[dopey20832]

big deal its not grounding in turn creating a static field around the cage...foo sheezy

[Johnsnyder666]

yeah i agree hook up a ground wire and lets see what happens

[Bathspud]

This was done at a special event done for young kids, to get them interested in science. So yeah, maybe it's not a big deal to you, but they're not doing this to impress you.

[Ish55]

dang i'd be freaked out in that cage

[Guthorm]

I love so much electrostatic machines to have namded my band "The Wimshurst's Machine"! Great video!!! :-D

[SOhio142]

PHYSICS ARE AWESOME!

[Gza330]

PHYSICS Rulesssssssssssss

[freeview11]

u wudnt b saying that if u picked A level physics and hav an exam in january!!

[kingbusch]

did she just say for sheezy right at the beginning??!! hahaha

[SOhio142]

shes speaking german u idiot!!

[SOhio142]

she said verschließen, which is the german verb that means to lock up (the guy is locked in a cage). You stupid!!

[ntipouan]

cool:)

[Booshibonton]

hmmm....ok....kinda cool... but who wasn't expecting that to happen?

[alt173]

But how does it work?

[mortichro]

PHYSICS ROCKS!!! :D
