Abstract
A superconducting magnet comprising a superconducting coil for generating a magnetic field when current flows therethrough and a vacuum heat insulation vessel storing and maintaining therein the coil at a cryogenic temperature, said vacuum heat insulation vessel having a part, such as a cylindrical outer wall, made of a ferromagnetic material which provides a path of high magnetic permeability for outwardly-directed flux lines of the magnetic field generated by said coil to reduce the spread of the flux lines and weaken the magnetic field outside the vessel.
