A magnetic resonance imaging (MRI) magnet includes different-diameter, longitudinally-proximate, first and second coil form segments. First and second superconductive coils are wound, respectively, around the first and second coil form segments. A first spacer ring is attached to the first coil form segment and longitudinally abuts a lateral side of the first superconductive coil, and a second spacer ring circumferentially surrounds and is attached to the second coil form segment and longitudinally abuts a lateral side of the second superconductive coil. Two or more circumferentially-spaced-apart plate members are attached to, and extend radially outward from, the first and second spacer rings.
