NEET Physics Magnetic Flux MCQ Question
Type: MCQ-numerical-Medium-Class 12
A square of side L metres lies in the xy-plane in a region, where the magnetic field is given by B = B₀(2î + 3ĵ + 4k̂)T, where B₀ is constant. The magnitude of flux passing through the square is
A
2B₀L² Wb
B
3B₀L² Wb
C
4B₀L² Wb
D
√29B₀L² Wb
Correct Answer
Option C
Detailed Explanation
The flux is given by B·A, where A is the area vector perpendicular to the xy-plane, so flux = 4B₀L².
