Question:

An example of a perfect diamagnet is a superconductor. This implies that when a superconductor is put in a magnetic field of intensity $\mathrm{B}$, the magnetic field $\mathrm{B}_{\mathrm{s}}$ inside the superconductor will be such that:

  1. $\mathrm{B}_{\mathrm{s}}=-\mathrm{B}$

  2. $\mathrm{B}_{\mathrm{s}}=0$

  3. $\mathrm{B}_{\mathrm{s}}=\mathrm{B}$

  4. $\mathrm{B}_{\mathrm{s}}<\mathrm{B}$ but $\mathrm{Bs} \neq 0$
