...f you try to calculate how many EMP weapons would be required to cover the country, you get close to looking at infinity.
Be afraid, be very afraid.
All wrong. In fact it takes one - more than that are actually counterproductive and the amount of time the field takes to hit & saturate is measured in billionths of a second (a shake in nuclear physics) No hype involved.
Nonsense.
All electromagnetic fields are subject to the same physical laws. Field strength diminishes as the square of the distance.
Try another sucker.
