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. directly proportional to $I^2$
• D. zero

Answer 1

The correct option is 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.
