E)none of the above.

Question

Quizplus · Accepted Answer

The Meissner effect is the phenomenon where a superconductor expels any magnetic field from its interior. This effect occurs because superconductors have zero resistance and therefore any magnetic field inside the superconductor would result in currents which would lead to energy dissipation. Therefore, the superconductor expels the magnetic field in order to maintain zero resistance and avoid energy dissipation.
