Question

The variation of intensity of magnetization left parenthesis I right parenthesis with respect to the magnetizing field (H) in a diamagnetic substance is described by the graph in figure.

  1. OD    
  2. OC  
  3. OB  
  4. OA  

The correct answer is: OC


    For a dia-magnetic substance, I is negative and negative I proportional to H. Therefore, the variation is represented by O C o r O D. As magnetisation is small, O C is better choice.
