One could make the case that maybe the magnetic fields don’t actually originate from him, but that his powers consist of an ability to manipulate, re-direct, and strengthen the existing magnetic fields in the environment. So he’s intensifying the Earth’s fields to hold up the disk, and there’s a third-law force-pair between the disk and the Earth. He could, in principle, pull the frog trick on himself, but maybe he’s not powerful enough to produce a field that strong. But this is pure fanwankery; **Otto** of course has the real reason for the disk (it just looks cool). The question is just then whether it was the writers’ aesthetic judgement that led to it, or Magneto’s.
