A) zero
B) \[\frac{{{\mu }_{0}}}{4\pi }\]
C) \[4\pi {{\mu }_{0}}\]
D) \[\frac{4{{\mu }_{0}}}{\pi }\]
Correct Answer: A
Solution :
According to Gausss theorem in magnetism, surface integral of magnetic field intensity over a surface (closed or open) is always zero, ie,\[\mathop{\int\mkern-20.8mu \circlearrowleft} \overrightarrow{B} .d\overrightarrow{A}=0\]
