The invention relates to a magnetic flux assembly (1) for closing a magnetic circuit of a relay (20), and a relay (20). A problem associated with known relays is that high magnetic forces and thus a high current in the control circuit or a high number of windings in the coil are necessary for switching, in particular if a load circuit connected to the armature is closed in the open position of the magnetic flux assembly. The object of the invention is to provide a solution that allows an easier switching, in particular with a lower current. This object is achieved by a Magnetic flux assembly (1) for closing a magnetic circuit of a relay (20), comprising a yoke (3), and an armature (4) that is movable relative to the yoke (3), wherein the yoke (3) comprises a coil part (31) that is adapted to be received in a coil (35), and a flux conduction part (36) that is adapted to conduct the magnetic flux generated by the coil (35), and wherein the armature (4) is U-shaped.
