The correct definition of Meissner effect is
- A the phenomenon of perfect paramagnetism in superconductors
- B the phenomenon of perfect diamagnetism in superconductors
- C the phenomenon of perfect diamagnetism in semiconductors
- D the phenomenon of perfect ferromagnetism in metals
Answer & Solution
Correct Answer
(B) the phenomenon of perfect diamagnetism in superconductors
Step-by-step Solution
Detailed explanation
Superconductors in the Meissner state exhibit perfect diamagnetism or superdiamagnetism, meaning that the total magnetic field is very close to zero deep inside them.
