JEE Mains · Physics · STD 12 - 5. Magnetism and matter
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
- A \(B_s\, =-B\)
- B \(B_s\, =0\)
- C \(B_s\, = B\)
- D \(B_s\, < B\) but \(B_s \ne 0\)
Answer & Solution
Correct Answer
(B) \(B_s\, =0\)
Step-by-step Solution
Detailed explanation
Magnetic field inside the superconductor is zero . Diamagnetic substances are repelled in external magnetic field
