Abstract: A magnetic field generation apparatus is provided for a magnetron including a permanent magnet arrangement and a magnetic field conductor device. The magnetic field conductor device has a diverting element. The diverting element, which includes a plurality of rectangular diverting segments, is arranged detachably on the magnetic field generation apparatus during maintenance work in order to deflect a magnetic field generated by the permanent magnet arrangement away from further components of the magnetic field generation apparatus and components of the magnetron. A magnetron includes a magnetron tube and such a magnetic field generation apparatus. In a method for replacing an old magnetron tube of such a magnetron with a new magnetron tube, the diverting element is arranged on the magnetic field generation apparatus, and the old magnetron tube is removed from the magnetron and replaced with the new magnetron tube in order to then remove the diverting element again.
