[en] The g-2 muon storage ring at Brookhaven National Laboratory will have a 1.7 meter long superconducting inflector magnet for injection of the muon beam into the storage ring. The field within the inflector is designed to be nearly zero. The inflector bucks out the main dipole field, but generates little or no stray field of its own. A portion of the field that remains is the field that is generated by circulating currents in the inflector magnet superconductor. Because the magnetization field has a different structure from field generated by the transport current, the magnetization field can adversely affect the field quality within the muon storage ring good field region. Correction of the effects of inflector superconductor magnetization and its effect on the good field region in the storage ring is discussed
