Which of the following figure best represents the variation of magnetic susceptibility ( χ) with temperature for a diamagnetic substance? (a) (b) (c) (d)

Answer: (c). For a diamagnetic substance χ is negative and independent of temperature. So the χ – T graph is a horizontal line below the T -axis. So the answer is (c).

Which of the following figure best represents the variation of magnetic susceptibility ( $\chi$ ) with temperature for a diamagnetic substance?

Show answer and solution

Answer: (c)

For a diamagnetic substance $\chi$ is negative and independent of temperature.
So the $\chi$ – $T$ graph is a horizontal line below the $T$ -axis.
So the answer is (c).
