Which outcome occurs when cryogenic pumps in an MRI unit lose suction?

💡 Explanation

A quench and magnetic field collapse occur because the **Joule-Thomson effect** cooling is lost when cryogenic pumps fail to compress helium, therefore the superconducting magnet rapidly warms, rather than maintaining its supercooled critical temperature, thus releasing latent heat.
