Torquers Are Not Propulsion!

If we have gone to all the effort of including magnetic torquers on our sail, then can we use the same equipment for propulsion?
Yes!
(In fact we can use the same equipment for many other tasks: radio receivers, magnetic field sensors, sail “actuators” that can turn the sail into a “rubber mirror”…)
