I am new here, first post! and have only just completed Yr12 physics so only have a basic understanding of this stuff so go easy if I'm wrong about anything.

So basically the idea of an EMP is to induce a high enough voltage in a target device/any wire in order to blow out/damage the circuitry thereby rendering the device useless. So my idea is the same as any other that has been presented to produce this effect, however I really just want to get to grips with the magnitude of power that is required to generate a change in flux large enough to produce this damage. So basically, charge up a bank of capacitors --> release in series --> pass through step down transformer --> antenna/wire/coil. That's my basic understanding of it :P

So assuming a circuit in a cell phone or other smallish device running on 3-5V lets say that I would like to produce an EMF of 6V in a wire in this device which we will speculate to be 10mm long and 2m away from source of this wave of energy. How would I calculate the required current to pass through a 1m length of wire/antenna in order to produce the necessary strength of field?

I am rather lost at the moment, playing around with EMF=BvL (assuming perpendicular to field) and EMF= change in flux/change in time and EMF=nBA2PIf etc. I really don't see how to work it out as most equations at my level of knowledge in physics tend to incorporate force in some way. I am also confused about velocity, as assuming that the target wire is stationary, then I can only see velocity being achieved from the movement of the wave produced over the wire (which is the speed of light?).

please don't go into 100% correct equations using integrals etc for correct magnetic field strength etc etc I am really chasing a basic understanding of the numbers involved and cannot be bothered :P

Thanks for any help guys, D
