There is one type of force-field "shield" that is possible. It is a
magnetic field that can shield a ship or station against certain types

Actually, there is already a force field in use that acts as an air valve
(plasma valve).

I see no reason why you couldn't create such shields of any arbitrary power
(e.g., Star Trek's deflector shields), except, of course, that the power
requirements would be beyond insane.
