Question

The product of magnetic susceptibility \( \chi \) and absolute temperature \( T \) is constant for a

• A. ferromagnetic material.
• B. diamagnetic and ferromagnetic material.
• C. diamagnetic material.
• D. paramagnetic material.

Hint:

For paramagnetic materials, the magnetic susceptibility is inversely proportional to temperature, and their product remains constant.

Answer 1

The Correct Option is D

Step 1: Understanding the relationship.
For paramagnetic materials, the product of magnetic susceptibility \( \chi \) and absolute temperature \( T \) is constant. This is known as Curie's law: \[ \chi T = \text{constant} \] Step 2: Conclusion.
Thus, the correct answer is \( \text{paramagnetic material} \), corresponding to option (D).
