You most definitely could corrupt the magnetic info without heat-- on
TV recently a science program featured an electromagnet that could
magnetise *Anything*, they even magnetically levitated a rat (which was
unharmed).
I don't think such powerful magnetic fields are commonly found though,
did I mention it took about 1MW of power to magnetise the space inside
the short four or so inch diameter tube space! They mentioned they could
levitate a human ie. simulate weightlessness but the magnet would draw
over 100MW thereby requiring a more or less dedicated power station, cost
maybe a few hundred million dollars or more, and it would be cheaper to
use the Space Shuttle anyway for weightlessness! Wow!!!
