The correct definition of Meissner effect is

Options

  1. Athe phenomenon of perfect paramagnetism in superconductors
  2. Bthe phenomenon of perfect diamagnetism in superconductors
  3. Cthe phenomenon of perfect diamagnetism in semiconductors
  4. Dthe phenomenon of perfect ferromagnetism in metals

Correct answer

B. the phenomenon of perfect diamagnetism in superconductors

Step-by-step solution

Superconductors in the Meissner state exhibit perfect diamagnetism or superdiamagnetism, meaning that the total magnetic field is very close to zero deep inside them.
