EMP generator

To make a EMP generator you will need:
A disposibul camera
alot of copper wire (the thiner the better)
A switch.

Step 1: Making the coil

You need to make a coil of wire about 10cm wide, you can do this by wrapping the wire around a circal object like a drink bottle. When winding go for thickness not whith, the thicker the coil the better. When finish wrapping slide it off the circal object and tape it up so it looks neat. Make shore to leave wire to connect it to your switch and power sorce. You should have a nice ring.

If I'm going to add more capacitors to it, should I do it in parallel or in series?

[nox1468]

if you want more capacitance (and thus a stronger pulse) attach in parralel. if you want more voltage tolerance (and thus a safer capacitor) use series.

This is better:

Just a suggestion, Check your spelling.

[Jewson]

Sorry about my spelling I just really suck, the best I've ever got in English at school is a C,

[firesirt]

I know the feeling (sigh) :'(

[eXtremeSomething]

yaeh me too

[Shweta Manoj]

Hay do u hav any video regarding hw to actually make it???

[Fingermouse]

Good effort, but.. bottom line: has anybody made an EMP which has demonstrably shown to work? And where is the link to it, for I, and many others would love to build it! ;-)

[Jewson]

ill post some more detailed photos soon

[assassino desigen]

ok prefect.
but what should i do for a stronger wave? add some extra wire?
or any other options?
i dident becse i think it would make the voltage lover is it tru or not?

[Jewson]

the more voltage you have the bigger the wave will be and with the wire the more the better untill you get to a certen point then it will drop. im not sure where the butter zone is yet, just dont go over kill.

[assassino desigen]

so sorry for very bad bad bad spelling

[McChicken]

Two things:

1) That won't put out an EMP, it's not even an electromagnet.

2) Your spelling is awful

3) My maths is awful

[Jewson]

If it isn't a emp then why dose it Work and behave exactly like one?

[samalert]

what i have seen is tat when EMP is created the device in its range are permanently damaged .....nw when u say knock off calculator is tat damaged permanently?

also what charge is supplied to this coil AC - DC ? and to what amount?

[Jewson]

Use dc, and the damage will depend on the strength of the device getting broken

[McChicken]

Does your H key work?
an EMP will not permanently damage an electrical device. It may be momentarily attracted to it, but there is no evidence for them being able to destroy circuits.

[waldosan]

actually there is, during the cold war when the united states was doing testing of nuclear weapons in the pacific the accidentally misjudged the strength of the weapon and found that the electrical systems in Hawaii were overloaded with thousands of volts melting their home appliances and causing damage to the island's infrastructure.

nuclear EMPs usually have a very small range compared to it's conventional blast, at surface level the conventional blast wave not only outpaces the EMP but it also envelopes it. however as you start detonating the nuclear weapon higher in the atmosphere you start seeing the range of the EMP increasing. 1 mile in the atmosphere could take out an entire state the size of say Kentucky. 2 miles could take out a good section of the breadbasket. 3 miles could take out anything not in a faraday cage or anything that isn't properly grounded device.

what happens with a nuclear emp is that the gamma rays "knock" electrons out of the air ionizing it and this forms a blast wave composed of the "knocked" electrons. this wave induces high voltages and currents in microchips as well as overloading the pigtails on telephone poles.

*spoiler* as a post script note: this is the concept that they were showing in call of duty modern warfare 2 when they blew up the space station.

however what they don't tell you is that properly grounding any circuit to earth will save most any circuit from an emp and anything with a microchip can be saved by "grounding" it to a Faraday cage that is grounded.

any transformer or coil will produce an emp, just like sparks will. if you hold up a radio to the light switch as you flick it on and off you can hear it's emp on a quiet station. the reason why electronics aren't affected wholesale by light switches is because the strength of the emp just isn't there. same with a coil like this, the energy is stored very briefly in the big huge electromagnet then when the magnetic field collapses because the current stopped then it transmits an electromagnetic wave which can be though of as an incredibly small EMP.

finally while we should promote good spelling and grammar i highly suggest you do it in a better way, just telling someone they are bad at grammar solves nothing but shamming the person. instead describe the proper usage of punctuation and vocabulary and above all else be a good example of proper spelling.

[Jewson]

I typed this up on a iPod so I have no keys

[lemonie]

Does this work for "knocking out" anything, i.e. have you broken a calculator with it yet?

L

[Jewson]

I haven't yet attached it to a disposable camera flash circuit, the one in the pic is a Brocken one but I have connected it to a 12v batterie and if I put a metal object in the magnetic feild it vibrats so much it fall off my hand. I recon if it is connected to a 330v capacitor it will be able to break a calculator Easley.

[waldosan]

this is an interesting device, i have always been interested in the possibility of moving electricity using wireless means, I don't quite understand how giving the coil a bigger radius while neglecting the surface area actually increases the EMP effect but i would suspect it has something to do with the actual collapsing of the magnetic wave.

[rimar2000]

Interesting. For what is this device?
