Magnetic Effects Of Current Question 9
Question 9 - 29 January - Shift 1
A single current carrying loop or wire carrying current I flowing in anticlockwise direction seen from $+ve z$ direction and lying in $xy$ plane in shown in figure. The plot of $\hat{j}$ component of magnetic field (By) at a distance ’ $a$ ’ (less than radius of the coil) and on yz plane vs z coordinate look like

Answer: (3)
Solution:
Formula: Magnetic field due to circular loop
$B_y=0$ in plane of coil
$B_y$ is opposite of each other in $-z$ and $+z$ positions.
