If you're worried about steel becoming magnetized, then think about
soft iron, which cannot.  Actually, magnetic fields drop off so fast
with distance that you probably don't really have to worry about stray
magnetic fields. (To the extent that a magnetic field looks like a
dipole field, it must fall off like 1/r**3.) For peace of mind, try
waving a magnet around an expendable floppy. You'll be impressed at
how close you have to get before you start seeing errors.
