The magnitude of magnetic flux density (B) at a point having normal distance d meters from an infinitely extended wire carrying current of I A is (μ0I)/(2πd) (in SI units). An infinitely extended wire is laid along the x-axis and is carrying current of 4A in the +ve x direction. Another infinitely extended wire is laid along the y-axis and is carrying 2A current in the +ve y direction. μ0 is permeability of free space. Assume î, ĵ, k̂ to be unit vectors along x, y and z axes respectively.
Assuming right handed coordinate system, magnetic field intensity, H at coordinate (2,1,0) will be
A
(3/2π)k̂ weber/m2
B
(4/3π)î A/m
C
(3/2π)k̂ A/m
D
0 A/m

Correct : c
