A single current carrying loop of wire carrying current I flowing in anticlockwise direction seen from + v e z direction and lying in x y plane is shown in figure. The plot of j ^ component of magnetic field ( B y ) at a distance a (less than radius of the coil) and on y z plane v s z coordinate looks like

Correct answer

2

Step-by-step solution

Magnetic field in plane of coil is B y = 0 The direction of j ^ component of magnetic field B y is opposite of each other in – z and + z positions. So, the variation of magnetic field is shown below.
