Nay. An MRI (magnetic resonance imaging) machine uses magnetism to align the electrons of hydrogen atoms (if I remember correctly)... Magnetism produces a current and has some effect on the electrical activity of the brain.
That's not to say the silly experiment is worth trying, though. I doubt there would be any appreciable effect caused by the magnet. Still, this forum reaches so many talented people I thought it might be worth suggesting.

Magnetism induces electricity and electricity induces magnetism. The magnetic field of the earth is caused by the molten metal (iron) core of the earth. This in turn affects polarized iron in nature, possibly because the cause of this em field is moving iron. In an MRI machine the electromagnetic field is induced by using electricity and running it through powerful magnets, and then shaped (or modulated) into an RF signal that makes the hydrogen molecules resonate, and depending on their natural spin, the difference in the resonance with the energy put in creates the picture, since we're talking particle spin effects.
In other words, yes, the powerful effects of the MRI work because our tissues already have their EMF and because we have learned to manipulate the electromagnetism to map these hydrogen atoms.
But the the value of the magnetic field of the earth, which is the cause of the iron's behavior when polarized, is already what it is, so that a magnet will only affect iron in tissue.
So a regular old magnet will only affect iron. And most of the iron in our bodies is in red blood cells.
However, I don't see any problem in such experiments, I do like magnets for pain control and have good results with one for my occasional wrist pain. So go ahead and let me know how it works out.
