ABSTRACT:
In an arrangement for adjusting the spatial dependence of a magnetic field in a working volume of a main field magnet (19) by means of ferromagnetic field shaping elements (16), the field shaping elements (16) are formed from foils (1, 5, 7, 8) and/or sheet metals (10) having openings (2, 3) whose shape, position and size are selected such that the shape and the amount of the remaining ferromagnetic material produces a desired spatial dependence of the magnetic field in the working volume of the main field magnet for appropriate positioning of the foils (1, 5, 7, 8) and/or sheet metals (10) relative to the working volume of the main field magnet.
