“…Among them, superconducting magnet (Klyukhin et al, 2019) technologies mainly include strong magnetic field magnets, magnetic levitation magnets and superconducting induction heating. On the other hand, superconducting strong electric applications mainly include superconducting cables (Arai et al, 2019), superconducting current limiters (Kar et al, 2012), superconducting transformers (Chen et al, 2018), superconducting generators (Magnusson et al, 2015), superconducting motors (Du et al, 2020) and superconducting energy storage (Zhu et al, 2018).…”
