The variation of magnetic susceptibility (χ) with temperature for a diamagnetic substance is shown correctly by graph (a) D (b) B (c) A (d) C

Answer: (c). Diamagnetic χ is negative and independent of T: a horizontal line below the T -axis. Graph A shows exactly this (B is positive constant, C is ferromagnetic, D is paramagnetic). So the answer is (c) A.

The variation of magnetic susceptibility $(\chi)$ with temperature for a diamagnetic substance is shown correctly by graph

Show answer and solution

Answer: (c)

Diamagnetic $\chi$ is negative and independent of $T$ : a horizontal line below the $T$ -axis.
Graph A shows exactly this (B is positive constant, C is ferromagnetic, D is paramagnetic).
So the answer is (c) A.
