The brain, and all aspects of the human body, are unaffected by an EMF. Even the blood, which contains iron in its haemoglobin, is non-magnetic and does not suffer. Long-term exposure (on the order of months) to extremely powerful fields, however, causes headaches and depression due to neurochemical imbalances. I imagine it also places strain on the microscopic deposits of iron found in the sinuses, assuming they actually exist (these deposits are partially the source of your "sense of direction", but I can't remember where I heard this from so it's possible it's complete nonsense/nonscience).

If anything were to happen in a supremely-powerful EMP field (aside from the fact that such a field could only be generated at point zero of a nuclear blast, rendering the rest of this discussion pretty moot), a person would merely suffer pain and the brain would shut down if the pain was significant enough, as a brain always does when it receives a massive pain stimulus. If the EMP was even larger, or was sustained, it would turn into coma as the brain wouldn't have a proper neurochemical balance to continue functioning consciously. If the EMP was unbelievably powerful (a star exploding at point zero), the brain would probably cease all functioning, resulting in immediate (relatively painless) clinical death, with no possibility to resuscitate.

That's my take, anyway. I'm not a qualified neurologist, though, so take it with a pinch of salt.

I dunno. Depends on your definition of "plausible". I think yours is more under the definition of "possible" than "plausible". Mine at least has a basis in science, using extrapolation from my limited knowledge on the subject. ;-)

I did, however, stick one of my Mom's hairpins in the wall outlet when I was six, in the hopes that it would give me super powers. The experiment was a complete failure, except for the unintended consequence of making me realize what a stupid six year old I was. Not my finest hour. Dead is not a superpower :|.

Whoa... you're dead? That causes me to seriously question this whole mortality thing. =/

There was this place I visited when I was a younger lad, it was this place with a huge level of natural magnetism in it, they did all sorts of weird stuff there to show you how it worked, it was pretty interesting. To the point though, my mother suffered horrible migraines while we were there and they promptly left after we left the area of question.

Uh no, it is quite easy my friends. We all know from House on Haunted hill that spirits can not only control electronics, but can connect to the internet, send e-mail and talk on live forums.
