NEET Physics Magnetic Field of Current Loops MCQ Question
Type: MCQ-conceptual-Medium
Two insulated concentric coils, each of radius R, placed at right angles to each other, carry currents I and √3I respectively. The magnitude of the net magnetic field at their common centre will be
A
μ₀I/R
B
μ₀I/2R
C
μ₀I/4R
D
2μ₀I/R
Correct Answer
Option A
Detailed Explanation
The net magnetic field is the vector sum of the fields due to each coil. Using the Pythagorean theorem, the resultant field is μ₀I/R.
