Abstract
Abstract A magnet coil device (1) for producing a magnetic field of a defined shape, for example, a homogeneous magnetic field for nuclear magnetic resonance techniques comprising at least four and preferably seven main coils (3) and a frame (2) comprising a cylinder of non-ferromagnetic material, in the periphery of which channels (7) accommodating the coils (3) are recessed.
