- $\frac{IA}{n}$
- $\frac{IA}{n^2}$
- $\frac{IA}{2}$
- $nIA$
- $IA$
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Magnetic moment $M$ for a single loop is the product of current and area.
Step 2: Meaning
For a coil with multiple turns, the total magnetic moment is the sum of moments of each turn.
Step 3: Analysis
$M = n \times (I \times A)$.
Step 4: Conclusion
The formula is $nIA$. Final Answer: (D)
