"Cryostats used in MRI machines are designed to hold a cryogen, typically helium, in a liquid state with minimal evaporation (boil-off). The liquid helium bath is designed to keep the superconducting magnet's bobbin of superconductive wire in its superconductive state. In this state, the wire has no electrical resistance and very large currents are maintained with low power input. To maintain sup… " - Cryocooler vs cryostat
