Which in this case would just be an incredibly strong magnetic field...

  What about neutral particles?

    Answer: inhomogeneous magnetic fields. See the Stern–Gerlach experiment. So basically your spaceship needs to have the core part in a spinning sphere generating such a magnetic field. Also not to forget the gravitational attraction which would make the free particles in space quite attracted to your bulk spaceship, following you like mosquitos :).
