I suggest you check the literature for particle accellerators,
especially linear accellerators. There's lots of good stuff there.

What you're asking for wasn't 100% clear to me, but...I recall
an article in a 1967 issue of Popular Science that showed a
magnetically propelled submarine, about 10 feet long, that
worked via (I think) the "Lorentz effect". One set of coils set
up a magnetic field in the conducting sea water, another set
set up an oscillating field opposed to the first set, and off
it went at about 1/2 mph. They specifically said it wouldn't work
in fresh water due to the lack of conductivity.

I've always wondered if you could do something similar using the
magnetic field of the earth as the first field.
