A single current carrying loop of wire carrying current I flowing in anticlockwise direction seen from + ve z direction and lying in x y plane is shown in figure. The plot of hatj component of magnetic field (By) at a distance ' a ' (less than radius of the coil) and on y z plane vs z coordinate looks like (A)  (B)  (C)  (D)

By​=0 in plane of coil By​ is opposite of each other in −z and +z positions.

$B_{y} = 0$ in plane of coil
$B_{y}$ is opposite of each other in $- z$ and $+ z$ positions.
