What is the Meissner effect associated with superconductors? It is
A)when the temperature above which the superconductor fails to work.
B)when the temperature at which the superconductors become perfect insulators.
C)when the net magnetic field within the bulk of the superconductor is zero.
D)when the net magnetic field within the bulk of the superconductor becomes nearly infinite.

Question

Quizplus · Accepted Answer

The Meissner effect is the expulsion of magnetic fields from the bulk of a superconductor. When a superconductor is cooled below its critical temperature, it becomes a perfect diamagnet, which means that it repels any magnetic field that is applied to it. As a result, the net magnetic field within the bulk of the superconductor is zero. This is known as the Meissner effect.
