Homogeneous magnetic field system comprising means for generating a magnetic field in the form of two substantially identical annular elements (1, 2) arranged coaxially to one another with a centre distance (L) less than the radii (r) of said annular elements, an element (3) for compensating the defects of the magnetic field, made of a tubular-shaped (3) ferromagnetic material and arranged coaxially to the annular elements (1, 2) generating the magnetic field (B).
