It sounds like you are trying to use magnetism of a coil or PM to counteract the magnetism of back-emf.
A magnet passing the face of the coil causes the coil to flip polarities during the pass. The coil will repel the rotor on the way in and attract on the way out. 1 magnet pass creates a full sinewave.
Meaning You would have to flip polarities of the counter-magnetic force dead center of each pass. If you used a physical magnet- the magnet itself would have to be un-sucked and flipped. And if you used another coil to do it, you will create flux (fluctuations of magnetism when flipping) which would induce the main coil.
And it seems to me you can not use a coil at all, because the magnetized core (from the rotor magnet and induced primary) will induce the coil you are using to counteract with.
Some more information and detailed images demonstrating the process would be handy here. I would like to see your method of dealing with all the snafu's present
