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

Answer 1

Answer: (D)

zero

Answer 2

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.
