- small, positive and varies inversely with temperature
- small, negative and temperature independent
- small, positive and temperature independent
- very large, negative and temperature dependent
very large, positive and temperature independent
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Paramagnetic materials are characterized by a small positive susceptibility.
Step 2: These materials do not retain magnetization in the absence of an external magnetic field, unlike ferromagnetic materials.
Step 3: According to Curie's Law, the susceptibility \( \chi_m \) of paramagnetic materials is inversely proportional to their temperature.
Step 4: Therefore, as the temperature increases, the magnetic susceptibility decreases, which aligns with option (A).
