Three identical bars A, B and C are made of different magnetic materials. When kept in a uniform magnetic field, the field lines around them look as follows: Make the correspondence of these bars with their material being diamagnetic ( D ) , ferromagnetic (F) and paramagnetic ( P ) :

Options

  1. AA D , B P , C F
  2. BA F , B D , C P
  3. CA P , B F , C D
  4. DA F , B P , C D

Correct answer

B. A F , B D , C P

Step-by-step solution

Diamagnetic materials are repelled in an external magnetic field. Bar B represents diamagnetic materials.
