If a magnetic material has magnetic susceptibility \( \chi = -0.5 \), then its relative magnetic permeability \( \mu_r \), and the type of material is
If a magnetic material has magnetic susceptibility \( \chi = -0.5 \), then its relative magnetic permeability \( \mu_r \), and the type of material is
Show Hint
\( \chi<0 \) $\Rightarrow$ diamagnetic, \( \chi>0 \) $\Rightarrow$ paramagnetic.

- \(0,\ \text{diamagnetic} \)
- \(2,\ \text{ferromagnetic} \)
- \(1,\ \text{paramagnetic} \)
- \(-1,\ \text{ferromagnetic} \)
- \(0.5,\ \text{diamagnetic} \)
Show Solution
Verified By Collegedunia
The Correct Option is
Solution and Explanation
Concept:
\[
\mu_r = 1 + \chi
\]
Step 1: Substitute.
\[ \mu_r = 1 - 0.5 = 0.5 \]
Step 2: Interpretation.
Negative susceptibility $\Rightarrow$ diamagnetic material.
Step 1: Substitute.
\[ \mu_r = 1 - 0.5 = 0.5 \]
Step 2: Interpretation.
Negative susceptibility $\Rightarrow$ diamagnetic material.
