This engineering study measures and simulates screening current induced magnetic fields (SCF) in a Bi2223-tape HTS insert used in an LTS/HTS NMR magnet at 77 K. SCF was induced by the insert self-field, an external 5-T background magnet, and their combination, and axial field distributions and temporal variations…
