Abstract
A magnetic system for nuclear magnetic resonance tomography devices, for generating a homogeneous magnetic field in a volume, has a surface surrounding the volume which is permanently divided into a number of non-overlapping surface elements, each surface element having structure for permitting one or more iron laminae to be attached to the surface element. For any given installation, known calculating methods are used to determine which of the surface elements are to have the laminae attached thereto to produce the desired homogeneous magnetic field.
