Assertion :A current continues to follow in superconducting coil even after switch is off. Reason : Superconducting coils show Meissner effect.
Options:
Answer:
B
Solution:
The assertion is true. Even when the emf is switched off, the current continues to flow because its resistance becomes zero. The Meissner effect is another property of the superconductor and not the reason for the assertion. Meissner effect repels the magnetic field lines from the interior of the superconductor. (b)
