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 B s inside the superconductor will be such that

Options

  1. AB s = B .
  2. BB s = 0 .
  3. CB s < B   but B s ≠ 0 .
  4. DB s = – B

Correct answer

B. B s = 0 .

Step-by-step solution

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