ABSTRACT:
A superconducting magnet configured for an NMR spectrometer includes a split type superconducting magnet having left solenoid superconducting magnets and right solenoid superconducting magnets with a center space therebetween for receiving a sample tube. A permanent current switch is provided and the left and right solenoid superconducting magnets are arranged symmetrically with respect to a center face of the center space. The left and right solenoid superconducting magnets are constituted by an outermost magnet and a plurality of innermost magnets and are arranged in concentric relation with respect to a vertical axis of the center space. A direction of current in at least one of the plurality of innermost magnets is minus when a direction of current in the outermost magnet is plus.
