An example of a perfect diamagnet is a superconductor. This implies that when a superconductor is put in a magnetic field of intensity B, the magnetic field Bs inside the superconductor will be such that
  1. Bs=B.
  2. Bs=0.
  3. Bs<B but Bs≠0.
  4. Bs=–B

Solution

In diamagnetic material, the magnetic field strength decreases. So, in a perfect diamagnetic, it has to be zero.
