The nature of the flow of a spin current which transports longitudinal magnetism of 3He-j5 through a narrow aperture has been studied. The experiments reveal a transition from a current-flow regime with phase relaxation to a hysteresis-free dependence of the current on the difference between the phase of the order parameter.
