Which outcome arises when a superconductor is exposed to a strong external magnetic field exceeding its critical field?

💡 Explanation

When a superconductor exceeds its critical magnetic field, superconductivity is destroyed as the magnetic field penetrates the material, disrupting the Cooper pairs and thus restoring normal resistivity because the Meissner effect breaks down. Therefore, restoration of resistivity occurs, rather than current flow, amplified Meissner effect or Cooper pair stabilization which require sustained superconductivity.
