Magnetic articles (10) are advanced in single file within a tube (14) for dispensing therefrom. A first magnetic device (20) establishes a magnetic field to releasably seize the leading article (10) such that trailing articles (10) are stopped in the tube (14). A second magnetic device (22) operates at a fixed location along the tube (14) and establishes a magnetic field to releasably seize the next trailing article (10) in the tube (14). A mechanism (40) then indexes the device (20) with the seized, leading article (10) a sufficient distance away from attraction of the second device (20) such that, when the leading article (10) is released by device (20), it is also released from tube (14).
