An NMR-grade superconducting magnet has been constructed which operates in persistent mode at 14.25 T at reduced temperature. The stored energy is 840 kJ. The magnet incorporates niobium-titanium and niobium-tin multifilamentary conductors. In the persistent mode all windings are in series with superconducting joints between sections. Six of the joints are hybrids, niobium-tin joined to niobium-titanium. The niobium-titanium windings reached short sample without training. The niobium-tin sections suffered two training quenches before reaching 14.25 T.>
