Question

For a paramagnetic material, the dependence of the magnetic susceptibility $\chi$ on the absolute temperature T is given by

• A. $\chi \alpha T$
• B. $\chi \alpha$ $constant\times T$
• C. $\chi \alpha \frac{1}{T}$
• D. $\chi =constant$

Answer 1

Answer: (C)

$\chi \alpha \frac{1}{T}$

$\chi$ $=$ $\frac{c{\mu }_o}{T}$ (standard equation)
$c=$ Curie's constant
${\mu }_o=4\pi \times {10}^{-7}$
$T=$ Alsolute Temperature
$\chi$ $\alpha$ $\frac{1}{T}$
