A circular loop of radius `R`, carrying current `I`, lies in `x-y` plane with its center at origin. The total magnetic flux through `x-y` plane is

A

``inversly proportional to R

B

directly proportional to R

C

zero

D

directly proportional to I

Text Solution

Verified by Experts

The correct Answer is:
C
The magnetic lines of force will be perpendicular to the xy plane and they form closed loops. The number of lines of force going in the -z direction will be equal to the number of lines of force going towards the +z direction. Hence the net magnetic flux through the x-y plane will be zero.
