← ScienceWhich outcome occurs when placing a superconducting coil carrying current near a metallic enclosure?
A)Persistent currents induced within enclosure✓
B)Radioactive decay accelerates in coil
C)Coil superconductivity abruptly stops
D)Enclosure emits terahertz radiation weakly
💡 Explanation
Persistent currents are induced due to magnetic flux changes caused by Lenz's law; therefore, electrons move to counteract the varying external magnetic field, rather than an increased radioactive decay, because superconductivity sustains current without resistance.
