Detailed explanation-1: -The first successful superconducting magnet was built by G.B. Yntema in 1955 using niobium wire and achieved a field of 0.7 T at 4.2 K.

Detailed explanation-2: -The superconducting magnet is the largest and most expensive component of an MRI system. The magnet configuration is determined by competing requirements including optimized functional performance, patient comfort, ease of siting in a hospital environment, minimum acquisition and lifecycle cost including service.

Detailed explanation-3: -The race to create the first whole-body MRI scanner began shortly thereafter, with both Damadian and Mansfield participating. Three years later, Damadian created the first whole-body human scanner in May of 1977. This system was named “Indomitable".

Detailed explanation-4: -The conductor used in nearly all modern superconducting MR scanners is niobium-titanium (NbTi) that becomes superconductive below 9.4°K. Each wire is composed of multiple NbTi microfilaments embedded in a copper core.
