Funny thing is how Iron Man vs. Magneto battled resulted in AvX (althought he could also create an electromagnetic shield to prevent Magneto from taking control of it) and also, not every metal is affected by magnetic fields, gold being one of them. But also, there's only enough iron in the body to make a small nail, it might be a little, but not very useful.
