Explain the Meissner Effect and describe the variation of critical magnetic field with temperature.
List the failures of classical free electron theory and mention assumptions of quantum free electron theory of metals.
Lead has superconducting transition temperature of 7.26 K. If the initial field at 0K is 50 × 10 3 Am-1 Calculate the critical field at 6k.
State the assumptions of quantum free electron theory of metals.
Describe the Meissner Effect and classify superconductors into soft and hard types using M-H graphs.
Calculate the probability of occupation of an energy level 0.2 eV above Fermi level at 27°C.
Final Answer: The probability of occupation of the energy level 0.2 eV above the Fermi level at 27°C is approximately: Very low, as expected—because it’s above the Fermi level and…
