Various ways of doing this have been proposed but none of them have been tested even in the laboratory. So many new and completely unknown technologies would have to come together for a interstellar fusion ramjet I would have to rate it least likely to ever be used.

Isn't the hydrogen condensed and fused into plasma by the Magfield?
Why would you need electrical charge for that?

I suppose we all thought that, in one way or another"
