At transition temperature the value of critical field is____________?
Correct answer: A. zero
- A. zero
- B. negative real value
- C. positive real value
- D. complex value
Explanation
The critical magnetic field falls to zero at the transition temperature because the material loses superconductivity at that point. Hence the value is zero rather than positive, negative, or complex.
