Corrector device for correcting unhomogeneities of the magnetic field (BO) produced by a magnet, said device applying a principle of correction of the field by means of one or a plurality of magnetic elements (A1, ..., AN) in a manner which is much simpler and quicker than in the prior art. To this effect, the corrector device of the invention comprises premachined openings (C1, ..., Cn) which are intended to house a magnetic element (A1, ..., AN) and comprises means (20) to maintain confound a longitudinal axis (8) of the magnetic element (A1, ..., AN) and a longitudinal axis (30) of the opening (C1, ..., Cn), independently of the value of the cross-section (S1) of the magnetic element (A1, ..., AN). |
