An electromagnetic pulsing ( EMP ) is a wave of energy that espouse atomic detonations and jeopardise to fry your personal electronics . Could something already in your abode preserve your electronics from an early demise ? Let ’s do this head as we front at the nature of electromagnetic pulses and if your microwave could foreclose damage from an energy attack .
Electromagnetic pulses and Faraday coop
If a atomic bomb is detonated mellow in Earth ’s atmosphere , the harm from the attack would not be in the form of vaporized buildings , but in the variety of a wide - scaleelectromagnetic pulse . With the EMP would come a voltage spike that would likely fry most electronics .
Ideally , a Faraday cage would divert the energy from an electromagnetic pulse and prevent damage to the electronics within . Faraday cages are containers made of aconducting fabric , typically copper or atomic number 13 sheets or mesh , with the conducting stuff alter the coalition of electrical charges inside to neutralize the incoming energy pulse rate .
Faraday John Cage are simple to make – the first consisted of a small room covered inmetal foil , with the enhancer successfully countering high - voltage waiver from an electrostatic generator and preclude change in the static environs inside . you could produce your own Faraday cage easily , but you belike have one – your microwave oven .
Your microwave as a Faraday cage
microwave work by exciting water molecule in food , translating to an increment in temperature . microwave oven ovens use non - ionizing microwave oven irradiation at a frequency of2.45 GHz(near therangeof your electric cell phone ) , induce water in the your leftover to absorb vigour . As the weewee particle steep vigor , the receive partial charges – a disconfirming charge at one end and a positive charge at the other , causing the particle to spin constantly . The water molecules start to strike each other , mail kinetic vigour out as heat .

If a microwave did not act as a Faraday cage , the Energy Department let out by the magnetron would electrocute your eyes as you watch out leftovers re - heat . If you front closely at the glass window , there are a serial publication of holes put in a metal concealment to act as one side of a Faraday Cage , but still allow you to view your slowly rotating intellectual nourishment . As a microwave oven uses energy with a frequency of 2.45 gigacycle , the wavelength of the energy is around 4 inches . As long as the holes in the viewing windowpane are less than that size the push is kept in the microwave , thanks to the three metallic element wall and metal mesh take in window .
Since your microwave can keep the energy it generates within it ’s three walls and a viewing porthole , it will do the same and keep anything inside of it ( your cell telephone set , iPad ) safe from the energy dispersed in an electromagnetic heart rate .
The walls of the microwave oven are made of conductive alloy , with the viewing yap similar to a mesh wall in a Faraday John Milton Cage Jr. , making a microwave oven a intercrossed Faraday cage . I measured the holes on my microwave oven and they make out out to 1 milimeter ; small enough to theoretically deflect a pulse with a frequency of up to300 GHz . An electromagnetic pulsation would give off energy with a sort of frequencies , but your microwave oven should block the bulk of them .
you may examine your microwave oven by placing a radio or prison cell phone inside of a microwave oven ( do n’t sour it on ! ) and check for sign . Can you call the telephone in the microwave ? How is your wireless reception once at bottom ? You are more than likely ineffective to make a call or get a signal . The character of electromagnetic energy used in a cubicle column or radio transmitting will be stronger , but your microwave oven might make for a good barrier against it . If you need to go even further , toss some electronic item you would need in a disaster in an old microwave and overlay it in pondering alloy tape to stop up your microwave oven - wrench - Faraday cage even more .
In the issue of an EMP , the cord of your microwave ( if plugged in ) could also act as a basis , further helping drop off any vigor . I would probably dress the electric cord or leave it unplugged so I did n’t actually zap my cell phone in the middle of the night . You could also buy a broken microwave oven and varnish it with extra metallic element tape measure on the bound to quickly make a Faraday cage for recollective - full term use .
Al foil vs. an EMP
A tatty and more portable alternative comes in the form of aluminum foil . Faraday ’s first experimentation in 1836 used metal foil , and if you wrap up a cell phone in aluminum transparency , communicating between the column and earpiece will be turn off off due to distribution of energy along the enhancer and it ’s many creases .
The video above is an experimentation slam testing the outgrowth ( feel free to make play of my Hulk physical body in the scope ) .
When one cell phone call a target earphone that is wrapped aluminum foil , the call is not take in . As cellular telephone phone calls are transmitted using a shape of non - ionizing electromagnetic actinotherapy ( stria in the range of 850 MHz to 1.9 GHz ) , this is a simple demonstration of a Faraday coop in action .
In the issue of an eminent EMP plan of attack , wrapping your electronics in aluminum foil might offer a modicum of protection . At the very least , wrap your headphone in aluminum foil will give plausible deniability for miss calls .
I ’ll probably would n’t jactitate my phone in the microwave every Nox – knowing myself , I would will turn it on and re - heat some coffee in the middle of the night , transmute my phone into a charge card brick . But , in a pinch , an unplugged microwave serves as a nice deterrent to an electromagnetic pulsation , and this attempt at debunkery fails . I doubt the mission on your telephone set will outlast the damage to your area ’s communication substructure , but you could play Angry Birds or read comics on your phone until the barrage fire run out .
