Q. The correct $I - H$ curve for a paramagnetic material is represented by, figure.
A) [image:5_image15.emf]
B) [image:5_image16.emf]
C) [image:5_image17.emf]
D) [image:5_image18.emf]
Explanation
(c) In a paramagnetic material, $I \propto H$. Therefore, the graph between $H\ and\ I$ is a straight line represented by choice (c) in figure.
