ABSTRACT:
Magnetic field generating apparatus for example for use in a nuclear magnetic resonance system comprises a first set of coils for generating a first magnetic field in a working volume outside the volume defined by the coils. A separate, second coil is provided spaced from the first set of coils for generating a second magnetic field in the working volume. The arrangement is such that the resultant magnetic field in the working volume is substantially homogeneous. An active shield coil may optionally be provided around the first set of coil.
