I don't know if the big magnet would rip something magnetic out of a 
person, but those big magnets are *dangerous.*

Few years ago I was talking to a MRI tech who told me about the time 
someone brought a steel E cylinder into the room in spite of all the 
warnings to keep iron out.  About 15 or 20 feet from the magnet the 
cylinder ripped loose at 50 g acceleration and went into the magnet 
bore at about the velocity of an 18th century cannon 
ball.  Fortunately nobody was in the way.  Took 6 days to cycle the 
magnet down, pull out the oxygen cylinder and bring the magnet back 
up to strength.
