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 inside the superconductor will be such that ______.
Options
Bs = -B
Bs = 0
Bs = B
Bs < B but Bs ≠ 0
MCQ
Solution
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 inside the superconductor will be such that Bs = 0.
Explanation:
Magnetic field inside the superconductor is zero. as χ = -1 for super conductors
∴ μr = 1 + χ = 1 - 1 = 0
so, B = μH = 0
