If you're slowing down the particles and generating a magnetic field, there's not necessarily any momentum transfered to the spacecraft. Kinetic energy can be exchange for a lot of stuff, heat, electric charge, and of course, an opposing force.

Just to pick one, look at kaseya. Unless everything on the network is locked down, it is going to find a way to connect to the server. Heck, by default it gives you a half dozen ways of remote viewing (mstsc, vnc,..) without manually installing anything beyond the small client package. It's very good software from a management perspective, but using it in a moderate size and diverse environment, it's border-line malicious.
