I believe magnetorquing can only change the orientation of a satellite and
not its orbit.  It is certainly used in the process of changing an orbit,
in order to get a thrusting device pointing in a direction where it will
do something useful. But by itself, it can't change an orbit.  It can help
point antennas in the proper direction, etc.
