You're quite right, of course, which explains why I was getting stupid figures when I tried to work out magnetic field strengths: it's the electric field doing the work, not the magnetic component.
I'd recommend not putting your Kindle at ground zero of an EMP-enhanced nuclear explosion too, though it is true that it is not known for certain that a Kindle would not survive this because it has not to my knowledge been tested
(I'm not sure what the amperage of the currents is. I was only able to find voltage figures: 15V.)
