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

A) directly proportional to l

B) directly proportional to R

C) directly proportional to \[{{R}^{2}}\]

D) zero

Correct Answer: D

Solution :

Since, here total flux entering equals the total flux leaving and hence net flux equals zero.
