    Abstract: A mechanism for selectively activating a plurality of downhole pathways including a) a valve having: i) a sleeve coupled for movement between an open and normally closed position; and ii) a valve magnet set mounted to the sleeve; and b) a dart for pumping in hole including a dart magnet set matched to the valve magnet set such that the dart couples to the valve when in close proximity and, in turn, the sleeve moves from the closed position to the open position.
