SOLENOID COIL FOR NUCLEAR MAGNETIC RESONANCE SIGNAL, AND PROBE FOR NUCLEAR MAGNETIC RESONANCE

PROBLEM TO BE SOLVED: To provide a solenoid coil for widening a sensitivity region by enhancing the uniformity of an outside static magnetic field from a solenoid coil end. SOLUTION: The solenoid coil includes: arranging a member for compensating the static magnetic field in a form for extending a main solenoid coil in an axial direction; and allowing the member for compensating the static magnetic field not to generate a high frequency magnetic field of a direction for canceling the high frequency magnetic field generated by the main solenoid coil. Concretely, the solenoid coil arranges a ring-like object comprising an insulator having the same sign as the magnetic susceptibility of the main solenoid coil so as to bring it into contact with the main solenoid coil in the outside of the axial direction of the main solenoid coil. In addition, the solenoid coil arranges a C-shaped member in the outside of the axial direction of the main solenoid coil or a plurality of ring-like members cut in a circumferential direction so as not to bring them into contact with the main solenoid coil.
