I'm not sure that this sm has a fixed magnet. I believe that the spring centers the vane (that's what the magnet does).
It also sets the tension on the vane. I would tighten the adjustment screw on the back till just keeps the vane centered. Any more than that will add resistance to the vane movement which the electromagnet will be fighting against.
