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 (A) directly proportional to I (B) directly proportional to R (C) inversely proportional to R (D) zero

A circular loop behaves like a dipole with one surface North pole and One surface south pole. The lines force emerges from N and will meet at S.So net flux through X - Y plane is zero.

directly proportional to I

directly proportional to R

inversely proportional to R

zero
