And lo, it came about, that on Mon, 18 Aug 2003 03:31:40 -0500 in
rec.crafts.metalworking , "Tim Williams" was inspired
to utter:

Do really high field strengths do anything wierd to the hemoglobin in
ones blood?

The iron is in a form which can't form magnetic domains, so it's
completely nonmagnetic. Also there is very little iron in the body
anyway, interestingly enough (I forget just how much).

I've read reports that some of the inks used in tatoos have enough iron in
them as to make the wearer "contraindicated" for MRIs. Something about
induction heating, I think it said. The researcher said he got some sample
inks and discovered he could move a drop of ink around using a magnet under the
piece of paper. neat, but ...

However, it will radiate a radio signal if excited properly (if I
understand the process right). ;-)
