Hi Robin, Can you supply a link? The only thing I can find with ion thrusters is that the magnetic field is used to prevent the ions from striking the side walls. I didn't find anything that suggests that a magnetic field can turn high energy ion trajectories from an omnidirectional source into unidirectional thrust. Magnetic fields only make the ion path curl.
