Question:
A paramagnetic substance is placed in a weak magnetic field and its absolute temperature $T$ is increased. As a result, its magnetisation
A paramagnetic substance is placed in a weak magnetic field and its absolute temperature $T$ is increased. As a result, its magnetisation
Updated On: Jun 20, 2022
- increases in proportion to $T$
- decreases in proportion to $\frac{1}{T}$
- increases in proportion to $T^{2}$
- decreases in proportion to $\frac{1}{T^{2}}$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The magnetisation
$I \propto \frac{1}{T}$
As temperature is increased the magnetisation decreases.
$I \propto \frac{1}{T}$
As temperature is increased the magnetisation decreases.
