Q. The variation of magnetic susceptibility $\mathcal{(X)}$ with absolute temperature $T$ for a ferromagnetic is given in figure , by
A) [image:5_image34.emf]
B) [image:5_image35.emf]
C) [image:5_image36.emf]
D) [image:5_image37.emf]
Explanation
(a) As temperature of a ferro-magnetic material is raised, its susceptibility $\mathcal{X}$ remains constant first and then decreases as shown in Fig. (a).
