1. A superconducting magnet assembly, comprising:
a magnet; and
a switch assembly coupled to the magnet, comprising:
a thermosyphon tube configured to carry cryogen therethrough; and
a switch configured to switch between a resistive mode and a superconducting mode, wherein the switch is in thermal contact with the thermosyphon tube; and
a first pressure valve and a second pressure valve,
wherein the first pressure valve and the second pressure valve are positioned on the thermosyphon tube and configured to control flow of the cryogen in the thermosyphon tube, and the switch is positioned between the first pressure valve and the second pressure valve,
wherein the magnet is configured to generate a polarizing magnetic field based on switching of the switch between the resistive mode and the superconducting mode.
