Don't try to read in an active MRI machine, since that is probably strong enough to rupture some of the spheres that implement the light/dark patterns on the display. (Well, actually, since a Kindle contains metal, it would basically turn into a sharp-edged flying brick if you did that, so... don't).
Minor nit, the display is electrostatically driven. No magnetic fields involved other than the very minor ones caused by micro-amp currents. Short of the type of fields involved in a EMP event, the type of magnetic field strength found outside of physics labs is unlikely to cause any issues for the display.
