A breakaway assembly comprising: a first connector; a second connector releasably couplable to said first connector, wherein said assembly is movable between a first configuration in which said first and second connectors are releasably coupled and together define a fluid path through which fluid is flowable, and a second configuration in which said first and second connectors are not coupled together, wherein said assembly is configured to move from said first configuration to said second configuration when a predetermined separation force is applied to said assembly; a closure valve (54, 80) positioned in one of said first or second connectors, wherein said closure valve (54, 80) is configured to be in an open position when said assembly is in said first configuration to allow fluid to flow therethrough, and to move to a closed position when said assembly moves to said second configuration to generally block the flow of fluid therethrough; an attraction member coupled to one of the first or second connectors; and a magnet unit coupled to the other one of the first or second connectors, wherein the attraction member and the magnet unit are magnetically attracted to each other when the assembly is in the first configuration to retain assembly in the first configuration, wherein the magnet unit includes a channel or channels (114, 116) that includes a plurality of magnets or a magnet received therein, wherein the magnets are positioned at an angle other than perpendicular relative to a radial line of the breakaway assembly in axial end view, and wherein a face corresponding to a pole of each magnet lies in a plane oriented parallel to a central axis of the assembly. a first connector; a second connector releasably couplable to said first connector, wherein said assembly is movable between a first configuration in which said first and second connectors are releasably coupled and together define a fluid path through which fluid is flowable, and a second configuration in which said first and second connectors are not coupled together, wherein said assembly is configured to move from said first configuration to said second configuration when a predetermined separation force is applied to said assembly; a closure valve (54, 80) positioned in one of said first or second connectors, wherein said closure valve (54, 80) is configured to be in an open position when said assembly is in said first configuration to allow fluid to flow therethrough, and to move to a closed position when said assembly moves to said second configuration to generally block the flow of fluid therethrough; an attraction member coupled to one of the first or second connectors; and a magnet unit coupled to the other one of the first or second connectors, wherein the attraction member and the magnet unit are magnetically attracted to each other when the assembly is in the first configuration to retain assembly in the first configuration, wherein the magnet unit includes a channel or channels (114, 116) that includes a plurality of magnets or a magnet received therein, wherein the magnets are positioned at an angle other than perpendicular relative to a radial line of the breakaway assembly in axial end view, and wherein a face corresponding to a pole of each magnet lies in a plane oriented parallel to a central axis of the assembly.
