摘要
A facility for generating a uniform magnetic field, particularly for generating a basic magnetic field of a magnetic resonance examination apparatus, particularly a medical magnetic resonance tomography apparatus, has a shim device with a guide device to or in which a number of ferromagnetic articles, such as balls, are movably attached. At least two of the articles have ferromagnetic properties differing from one another, such as saturation magnetizations that differ in magnitude from one another. A method for improving the homogeneity of a magnetic field makes use of such a facility.
