Q. The variation of magnetic susceptibility $\mathcal{(X)}$ with temperature for a diamagnetic substance is best represented by figure
A) [image:5_image19.emf]
B) [image:5_image20.emf]
C) [image:5_image21.emf]
D) [image:5_image22.emf]
Explanation
(d) For dia-magnetic substances, the magnetic susceptibility is negative, and it is independent of temperature. Therefore, choice (d) is correct in figure.
