<p>A magnet system (1) for a nuclear magnetic resonance (NMR) apparatus comprising a magnetic core arrangement (7, 13, 15) shaped to provide two or more discrete gaps (3, 5) in which objects to be imaged may be placed, the magnetic field across each gap being produced by a single drive coil arrangement (9) associated with the core arrangement. A system providing gaps, e.g. of different sizes, for different types of NMR examination is thus provided at relatively low cost compared with using a separate magnet system for each type of examination.</p> |
