← ScienceWhich outcome arises when a powerful external magnetic field collapses rapidly around a fault-bearing submarine cable?
A)Cable temperature approaches absolute zero
B)Increased dielectric breakdown risk occurs✓
C)Superconductivity becomes temporarily viable
D)Cable tensile strength improves momentarily
💡 Explanation
Increased dielectric breakdown risk occurs because rapid field collapse induces large voltage spikes via Faraday's law of induction. This induces extremely high electric fields therefore exceeding the cable insulation's dielectric strength, rather than other temperature-dependent or materials processes.
