Abstract

Apparatus for varying the magnetic field in a magnetic resonant element which comprises a magnetic yoke with one or more magnets mounted within the magnetic yoke so as to generate a substantially uniform magnetic field in the magnetic yoke and a plurality of magnetic resonance elements located in the magnetic field formed by the magnet and including adjusting means for varying the magnetic reluctance between the magnetic yoke and the magnet at a position which is opposite the position of the plurality of magnetic resonance elements. The magnetic reluctance can be varied to arrive at the desired strength of the magnetic field.
