Q127 / 197 · NEET 2009 (Mains) · Physics

If a diamagnetic substance is brought near the north or the south pole of a bar magnet, it is :

  • A
    Attracted by both the poles
  • Correct answer
    B
    Repelled by both the poles
  • C
    Repelled by the north pole and attracted by the south pole
  • D
    Attracted by the north pole and repelled by the south pole

Solution

As diamagnetic substances have negative intensity of magnetisation, they are weekly repelled by the external field.

Hence, the correct answer is option: 'B'.
