Abstract
In a magnet system, e.g. for use in a magnetic resonance apparatus, wherein a magnetic field is produced in a gap between pole pieces (5) joined by a yoke (7) by an electric drive coil arrangement carried on the yoke, stabilisation against variations in the field in the gap is provided by a stabilising arrangement (43) wherein over a section of its length the yoke is divided into a plurality of discrete parallel finger-like portions (45) each of which is surrounded by a separate ring (47) of superconducting non-magnetic material.
