Abstract
A magnet for use in medical magnetic resonance studies and having a pair of ferromagnetic pole pieces supported by a ferromagnetic yoke which establishes a flux return path. Columns of the yoke are configured to maintain the magnetic field within the columns approximately constant in every cross section of the columns and to maximize access to the magnet gap.
