ABSTRACT:
A nuclear magnetic resonance device for use in diagnostic procedures on the uman body is provided and comprises longitudinally extending cylindrical or rectangular crossectioned rare earths permanent magnets provided with cladding magnets extending longitudinally therewith and providing flux control for the establishment of a uniform flux field. Bucking magnets and other supplemental magnetic elements are provided to as precisely as possible control the magnetic flux field effected for the diagnostic procedures.
