Doubtful. If there is a real thrust and not an experimental error, most likely what it is doing is the standing EM field being generated is receiving a torque from geomagnetic field lines.

Problems are,
You can do the same thing with much less effort with a superconducting electromagnet.
and
It quickly loses effect the further away you go from a magnetic source (planet sun etc.). Might be useful in LEO station keeping but not much further beyond.

I believe it's probably a Lorenz force effect. We'd have to get it out of a magneto/gravitational field to test it.
