Clarify this
In the movies, they always explain Magneto's power by saying 'he can control metal'.
My understanding was always that in fact it is magnetic fields that he manipulates.
These are two very different abilities with different implications.
So which is it?
If it's just metal, then some of the complaints about his ability to pull himself toward metal objects and fly etc. make sense. But if he can control magnetic fields his powers should be far more broad. He should be able to generate/disrupt electrical activity, for instance.
