For a linear material, the relation between the relative magnetic permeability \( \mu_r \) and magnetic susceptibility \( \chi \) is:
Show Hint
For linear magnetic materials, the susceptibility \( \chi \) is related to the relative permeability \( \mu_r \) by the equation \( \chi = \mu_r - 1 \).
Updated On: Apr 7, 2026
- \( \chi = \mu_r + 1 \)
- \( \chi = \mu_r - 1 \)
- \( \chi = \mu_r \mu \)
- \( \mu - 1 \)
- \( \mu = \mu_r + 1 \)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1:
For a linear material, the relation between magnetic susceptibility \( \chi \) and relative magnetic permeability \( \mu_r \) is:
\[
\mu_r = 1 + \chi
\]
Step 2:
Rearranging this equation gives:
\[
\chi = \mu_r - 1
\]
Thus, the correct relation is \( \chi = \mu_r - 1 \).
