Yes you would still need oil.
"impart force":
Like magnetic poles repel and, according to the maths, the force with which they repel is squared as the distance between them decreases:
So Force = Magnetic Constant /Distance squared.
So the maths says; when D is 0; F is infinite, regardless of how strong the magnet is...

ie: You will still get all the force/torque, but without the gears ever physically touching, much like you can't get the like poles of a bar magnet to ever touch... theoretically..?
