Which outcome predictably occurs when a superconducting electromagnet quenches?

A)Magnetic field collapses rapidly
B)Cryostat temperature decreases sharply
C)Persistent current remains constant
D)Magnetic flux becomes highly concentrated

💡 Explanation

When quenching occurs, the superconductivity is locally lost, causing resistive heating. This, by Ohm's law and Lenz Law, causes the induced current to dissipate, therefore destabilizing the magnetic field rather than allowing it to condense or remain constant as current is converted non-superconductively
