EMPs are nuclear missiles detonated in the upper atmosphere would be very hard for you to make and then limit to 50m

just put about 50 inductors in sequence powered by 8509 standard car batteries, attach all that to a light bulb and when you complete the circuit a burst of fire and lightning will shoot out exactly 50m in all directions rendering electronics useless

You need to get a 15 killstreak then press right on the D-pad.
