Or Mercury's prosthetics could not have a magnetic field in the first place for her to manipulate, after all not every metal is ferrous and there are several non-ferrous metals that would not entirely work with Pyrrha's polarity, for example although Aluminum is magnetic to an extent, it does not contain enough iron to have a magnetic field. Copper and Zinc are other examples of non-ferrous metals that could possibly ignore Pyrrha's Semblance, but this is just an idea, after all who knows what Mercury's prosthetics are even made of. For all we know they might be made from some fictional super-alloy that's lighter and stronger than Titanium that contains little-to-no iron to make it efficient in not interacting with the vector of magnetic fields or something like that.
