The variation of susceptibility ( $\chi$ ) with absolute temperature ( $T$ ) for a paramagnetic material is represented as:

Option 1

Option 2

Option 3

Option 4

Identify the Law: The relationship between magnetic susceptibility ( $\chi$ ) and absolute temperature ( $T$ ) for a paramagnetic material is governed by Curie's Law.
Formula: The law states that susceptibility is inversely proportional to the absolute temperature: $\chi = \frac{C}{T}$ where $C$ is the Curie constant.
Graphical Representation: The equation $\chi \propto 1/T$ represents a rectangular hyperbola. As the temperature ( $T$ ) increases, the susceptibility ( $\chi$ ) decreases non-linearly. The correct graph should show a curve starting high on the y-axis and approaching the x-axis asymptotically as $T$ increases.
