[X-Men: Days of Future Past] If Magneto was able to lift a hundred-thousand ton stadium, wouldn't he be able to escape prison by affecting some distant metal?

Young magneto can lift a stadium, older Magneto can lift the Golden Gate Bridge, both of which weight several hundred thousand tons.

Even though he was buried deep beneath the Pentagon, can't he attract some metals from the surface or some iron ore inside the soil to escape?

Can Magneto sense the presence of metal without using any of his natural senses? It might be a focus thing. If he can't see the metal, he can't visualize himself moving it. That's one of the reasons he uses those big arm gestures, at least in the movies. He's not physically lifting anything, but the motion of his arms helps him concentrate on how he wants to manipulate the metal.

Imagine sculpting with numb hands and arms, and a blindfold. It'd be hard enough just finding the clay or the table, to say nothing of actually turning it into anything.
