← ScienceWhich consequence results when cryogenic fluid supply abruptly stops to a superconducting magnet?
A)Flux flow causes resistive heating✓
B)Critical current density abruptly drops
C)Magnetic field homogeneity improves
D)Cryostat pressure decreases rapidly
💡 Explanation
A quench occurs because the temperature rises beyond the superconducting transition, which then causes flux motion/energy dissipation through flux flow, rather than maintained superconductivity; therefore resistive heating results rather than other changes relating to the magnet’s field properties.
