Question:
The magnetic dipole moment of a current loop is independent of
The magnetic dipole moment of a current loop is independent of
Show Hint
Dipole moment is a property of the loop itself, independent of external fields.
Updated On: Apr 10, 2026
- magnetic field in which it is lying
- number of turns
- area of the loop
- current in the loop
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Formula
Magnetic dipole moment $M = NIA$.
Step 2: Variables
From the formula, $M$ depends on the number of turns ($N$), current ($I$), and area ($A$).
Step 3: Conclusion
The external magnetic field does not appear in the definition of the dipole moment itself; it only determines the torque acting on that moment.
Final Answer: (a)
