Q149 / 180 · COMEDK 2024 (Evening Shift) · Physics
For a paramagnetic material, the dependence of the magnetic susceptibility $\chi$ on the absolute temperature is given as
- AIndependent of $\mathrm{T}$
- Correct answerB$X \propto\dfrac{1}{T}$
- C$X \propto T$
- D$X \propto \dfrac{1}{T^2}$
Solution
According to Curie's Law, the magnetic susceptibility $\chi$ of a paramagnetic material is inversely proportional to its absolute temperature $T$.
The mathematical expression for Curie's Law is given by $\chi = \dfrac{C}{T}$, where $C$ is the Curie constant.
Therefore, $\chi \propto \dfrac{1}{T}$.
Answer: $X \propto\dfrac{1}{T}$
The mathematical expression for Curie's Law is given by $\chi = \dfrac{C}{T}$, where $C$ is the Curie constant.
Therefore, $\chi \propto \dfrac{1}{T}$.
Answer: $X \propto\dfrac{1}{T}$
Hence, the correct answer is option: 'B'.
