Depending on the military application, it might still have a halo effect. Great skill in manipulating magnetic fields would probably be useful for: MRI. Detecting landmines and UXO in a field from a UAV or otherwise safe distance. Detecting submarines, including those by terrorists or rogue states transporting NBC weapons. While those are military applications, they're fairly unalloyedly positive. Even the hypothetical plasma rifle isn't necessarily a bad thing; if a plasma rifle allows rich countries like US, Japan, etc. to overmatch poor countries and thus prevent war, that's kind of a plus.
