Question:
The magnetic susceptibility of a diamagnetic material is
The magnetic susceptibility of a diamagnetic material is
Show Hint
Diamagnetism is a universal property but is often masked by stronger paramagnetism or ferromagnetism. The negative sign signifies the repulsion from magnetic poles.
Updated On: Jun 24, 2026
- positive and small
- negative and small
- positive and high
- zero
- negative and high
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Magnetic susceptibility (\(\chi\)) measures how easily a substance becomes magnetized in an external magnetic field.
Step 2: Detailed Explanation:
1. Diamagnetic substances: They develop weak induced magnetization in a direction opposite to the external field. Thus, their susceptibility is negative and small (e.g., \(-10^{-5}\)).
2. Paramagnetic substances: They develop weak magnetization in the direction of the field. Susceptibility is positive and small.
3. Ferromagnetic substances: They develop strong magnetization. Susceptibility is positive and very high.
Step 3: Final Answer:
The magnetic susceptibility of a diamagnetic material is negative and small.
