  1. Question 1

    Q1. A superconductor has a critical temperature of 4 K. At 2 K, the critical magnetic field is 10^(-2) T. What is the critical field at 0 K?

    • A) 1.33 * 10^(-2) T
    • B) 1.25 * 10^(-2) T
    • C) 1.5 * 10^(-2) T
    • D) 2 * 10^(-2) T

    Answer: 1.33 * 10^(-2) T

    Explanation: Using the relation H_c(T) = H_c(0) * [1 - (T/T_c)²], we can find H_c(0).
