Abstract

A magnetic shield for a field magnet of a magnetic resonance system is provided. A magnet apparatus with a field magnet for a magnetic resonance system with active shielding and a magnetic shield, wherein the magnetic shield forms a hollow body which accommodates the field magnets is also provided. A wall of the hollow body has a first, a second and a third area, which are disposed along the axis. In this case the second area separates the first area and the third area from one another and has a smaller wall thickness than the first and the third area.
