If there's nothing around the pointer dragging, its probably picked up a
bit of steel held in the air gap by the magnet. Sometimes those can be
cleared up with masking tape folded sticky side out and slide into the
gap, these days double faced tape might work. The last meters I got into
didn't survive my touch. In the past, places that repair and calibrate
test equipment, like Scherrer Instruments on Manchester in St. Louis had
men who could take meter movements apart and fix them. But I've not
tried to get that done in a long time.
