There is Iron in blood. Iron is magnetic. Roughly how strong would a magnet have to be to induce a noticeable attraction? It would be nice to know this for several distances. Also, do electromagnets that strong exist?
Humans are weakly diamagnetic. Rather than being attracted by a magnetic field we would tend to repel the lines of force.
Look at the work of the High Field Magnet Laboratory http://www.ru.nl/HFML/, in particular http://www.ru.nl/hfml/research/levitation/diamagnetic/ where they demonstrate levitation of a living frog. It took about 16T to levitate the frog.
WEll hi !!! mainly the iron in the blood is incoperated with other components. in the blood plasma may be those forces of attraction are a lot stronger than the forces of attraction between a magnet and a magnetic component. well if it comes to bonds they are the strongest forces and I guess, so to have a magnet strong enough to attract human we will have to first break all the bonds between the haem and globin and thats quite not easy at all
well then its purely my guess !! :P
