Abstract: A clutch has a stationary carrier, a first clutch member and a second clutch member. The first clutch member and the second clutch member are disposed so as to be rotatable about a common axis. The carrier has a coil arrangement, which is partially accommodated in a first partial core containing soft iron and which faces towards the first clutch member. The first clutch member has a second partial core, containing soft iron, having magnetic-flux poles that at least partially enclose the coil arrangement of the stationary carrier. The second clutch member has permanent-magnet elements, which face towards the magnetic-flux poles and which, are at least partially in alignment with at least some of the magnetic-flux poles. The first clutch member and the second clutch member are set up to transmit a torque and/or a rotary motion from the one clutch member to the other clutch member.
