Question:

A material behaves as a superconductor below a critical temperature \( T_c \) and as a normal conductor above \( T_c \). A magnetic field \(\overrightarrow{B} = B\hat{z}\) is applied when \( T > T_c \). The material is then cooled below \( T_c \) in the presence of \( \vec{B} \). Which of the following figures represents the correct configuration of magnetic field lines?
