If the city suddenly cuts the EM field off - even if Mags draws power from Jupiter or wherever - it won't be getting into the city.
Because for all intents and purposes, the concept of 'magnetism', just like the concept of 'gravity', is fast and loose when Jack asks the city. Boost it by 5000%? Sure, why not. REDUCE it by 5000%? Cool.
So it's not Jack's control of the city's EM field that Mags is fighting against. It's the city controlling its own EM field. It can remove it, just like it can remove gravity.
that's the thing, i don't know that it could, or even if it could that it would matter. mags' reach far exceeds the city limits and he has already shown planetary levels of control. could a city prevent him from accessing his power? like i said, i guess it isn't impossible, but it seems unlikely to me. more to the point--if the city could adjust its own em field so easily, why did it need to employ amps to do it? it should have simply been able to amp it without external sources since, as you say, it is 'its' em field after all....
