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

Directly proportinal to `I`

B

Directly proportional to `R`

C

Directly proportional to `R^(2)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
Circular loop behaves as a magnetic dipole whose one surface will be `N`-pole and another will be `S`-pole. Therefore magnetic lines a force emerges from from `N` will meet at `S`. Hence total magnetic flux through `x-y` plane is zero.
