Question
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
✓
Answer
Magnetic field inside the superconductor is zero . Diamagnetic substances are repelled in external magnetic field
