Which phenomenon prevents current flow above critical field?

💡 Explanation

Magnetic field penetration disrupts superconductivity because the Meissner effect is overcome, therefore the magnetic field penetrates into the material, rather than remaining excluded, which restores normal resistivity at higher fields.
