description Devices are provided for aligning magnetic or magnetizable particles, which particles are contained in a coating that is applied on one side of a substrate, which substrate is in the form of a web or sheet. The device has a magnet cylinder, which is arranged in a transport path of the substrate to be conveyed and, in a region of the outer circumference of the magnet cylinder, the device has a plurality of devices for effecting a magnetic field, or magnet devices for short. Some or all of the magnet devices comprise a magnet which is rotatable by an associated motor. The magnet cylinder is rotatably arranged in frame walls of a frame. At least one transducer for contactless transfer of electrical energy or control signals from the outside is provided in or on the rotating magnet cylinder, which comprises a first transducer part fixed to the frame and a second transducer part fixed to the cylinder during operation.
