Abstract
A magnetic coupling for a device, such as a cathode, which is received in a vacuum bulb of a tube which has shafts for mounting the tube for rotation on an axis, has an inner ferromagnetic part disposed in the vacuum bulb and connected to the device and an outer ferromagnetic part which is arranged outside of the vacuum bulb and aligned with the inner part. The outer part comprises a magnetic arrangement having a plurality of pole pieces to which the poles of a ferromagnetic yoke that forms the inner part are allocated.
