Any ionozed atom reacts to a magnetic field (since it has charge). I always
assumed a Bussard ramjet requires a *big* electromagnetic scoop, but perhaps
not. As an aside, I believe all attempts to produce sustained fusion
reactions have involved putting an isotope of hydrogen in an electromagnetic
containment bottle and then heating the resulting concoction to extreme
temepratures, usually with some kind of laser.

JDF has convinced me that a ramjet only works for breaking.
