Abstract
A superconducting magnet for producing a uniform magnetic field, including a main coil comprising first superconducting coils, and active shield comprising second superconducting coils and arranged in such a manner as to coaxially surround the main coil, and a self-shield comprising magnetic material and arranged in such a manner as to coaxially surround the active shield. The magnetic moment of the active shield is smaller in absolute value than and opposite in direction to the magnetic moment of the main coil.
