Googlize it. It's true.
Did.
Bing.
Still, “a little wrong”.
As I suspected (having extensive lab work in instrumental chemical analysis), the MRI does no \source\ the metal and can only affect (”move”) metal in the human body if that metal is already there - surgical implants or shrapnel.
If it does “move” metal (that is already there) it will always move, as a whole, toward the magnet and not “shoot” through the body.
