What happens if the helium level in an MRI gets too low? - Quora
WebAnswer (1 of 2): If helium level becomes so low that it is not enough to cool superconductor down, “quench” can happen. Normally, when properly cooled (around +4 Kelvin), wires become superconductor, which means they have no resistance to current. So you pump up high currents into conductor, whi...
