Abstract
A magnet, such as a closed, superconductive, magnetic-resonance-imaging (MRI) magnet includes a main coil, a correction coil, and a shielding coil positioned radially outward from the main and correction coils. Two magnetizable members are positioned radially outward from the main and correction coils and radially inward from the shielding coil to shorten the magnet, to supplement the strength, and increase the homogeneity of, the magnetic field created, at least in part, by the main and correction coils and to supplement the shielding provided, at least in part, by the shielding coil.
