Magnetism Question 291
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:
Options:
A) $ B _{s}=-B $
B) $ B _{s}=0 $
C) $ B _{s}=B $
D) $ B _{s}<B $ but $ Bs\ne 0 $
Show Answer
Answer:
Correct Answer: B
