<p>A magnet assembly, particularly for use in magnetic resonance imaging apparatus, comprises a number of electrical coils (1-6) arranged around and asymmetrically along an axis (8). The relative axial spacing between the coils (1-6) and the fields they generate in use is such that a substantially uniform magnetic field is generated in a homogeneous region (10), the centre (11) of the homogeneous region being offset from the geometric centre (121 of the assembly.</p> |
