An electromagnetic actuator for actuating a gas-exchange valve in a reciprocating internal combustion engine, the electromagnetic actuator comprising: an armature which is operatively connected to the gas-exchange valve; two electromagnets, each having a pole face; two oppositely oriented restoring springs; wherein the armature is guided in a reciprocating manner counter to the force of the two oppositely oriented restoring springs between the pole faces of the two electromagnets whose current supply can be controlled by a control device, the two electromagnets being disposed in mutual spacing and acting as opening and closing devices; and at least one additional mass which is associated with the gas-exchange valve and can be guided so that it is movable relative thereto and in the same direction of the gas-exchange valve, the at least one additional mass entering into operative connection with the gas-exchange valve, in the final phase of the armature's motion in the direction of a respective one of the two electromagnets, via a coupler.
