Yeah, I think this is the best answer. It also technically means that the Aurora Borealis is just the solar wind bouncing off our deflector shield, which is a pretty badass way to talk about that.

The other example that’s arguable at this point is the magnetic confinement systems inside fusion reactors, which use powerful magnetic fields to constrain the hot plasma, to keep it away from the walls of the reactor. It’s basically the same principle, but in that case it’s actually a human-made field. It still only affects ions, though, which is pretty different from most sci-fi force fields.
