A circular loop of radius R carrying current I lies in x-y plane with its centre

Question

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

Options:

A . Directly proportional to I

B . Directly proportional to R

C . Directly proportional to

D . Zero

Answer: Option D
:
D
Circular loop behaves as a magnetic dipole whose one surface will beN-pole and another will beS-pole. Therefore magnetic lines a force emerges fromNwill meet atS. Hence total magnetic flux throughx-yplane is zero.
