Powder brake
When no current flow in the magnetic coil, powder is being attached to in put drum side by centrifugal force as separate in put drum and out put drum. So the torque is not transmitted. If coil is exited by electric current, magnetic flux is generated, then torque is transmitted by the friction between powder and working side.
