Superconducting Magnets

Niobium-tin wire (Bell Labs, 1961) carries huge currents without loss, making very strong magnets for accelerators, MRI and fusion machines.

John Kunzler and colleagues showed in 1961 that Nb3Sn wire stays superconducting in fields above 8 tesla; niobium-titanium became the workhorse. The LHC, MRI scanners and large fusion devices all rely on such magnets.
