Magnet strong enough to rip the iron out of your body feasible?

+7
−0

Is it possible, given a strong enough magnet, to rip out iron based molecules out of the blood stream/body of a person/animal? Would such an event be the thing that kills someone or are there other adverse effects that would kill a person. I've seen reports of dizziness and metallic taste during MRI scans, but it's not fatal, and AFAIK, the effects of strong magnets on a vertebrate have not been tested.

Actually, they have been tested. I've seen a video of a frog being held in a magnetic field strong enough to keep it suspended in air without touching any object.

DonielF's very good answer mentions this, but I feel that the obvious (and common) misconception behind the question is also worth highlighting clearly here: Iron in its metallic form is strongly magnetic. Iron-containing biomolecules are generally not more magnetic than most other substances (i.e., hardly at all). Hence the silly-sounding extremes reached in the factual answers below.
