Which outcome occurs when an MRI machine's superconducting magnet quenches unexpectedly releasing stored magnetic field energy?

💡 Explanation

When an MRI magnet quenches, resistive heating occurs due to sudden loss of superconductivity and rapid energy release resulting in the flash boiling of liquid helium causing extreme overpressure. Therefore, rapid helium boil-off and consequent overpressure result, rather than sample damage, demagnetization, or data corruption which require unrelated processes.
