Superconducting magnet magnetically levitated transportation apparatus
 A superconducting magnet includes a superconducting coil, an inner tank for containing the coil, a shield plate for covering the inner tank, and an outer tank for accommodating the superconducting coil, the inner tank and the shield plate. The inner tank is supported on the outer tank by a load support member and the outer tank forms a vacuum vessel. At least one of the inner tank, the load support member, the shield plate and the outer tank includes a detection arrangement for detecting abnormality and/or deterioration of the inner tank, load support member, shield plate and outer tank associated with the respective detection arrangement.
