Question

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 $\hat{j}$ 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

MARKS Content Team · Accepted Answer

Correct answer: (C). 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.
