Q. The net magnetic flux through any closed surface, kept in a magnetic field is
A) Zero
B) $\frac{\mu_{0}}{4\pi}$
C) $4\pi\mu_{0}$
D) $\frac{4\mu_{0}}{\pi}$
Explanation
(a) According to Gauss’s theorem in magnetism, surface integral of magnetic field intensity over a surface (closed or open) is always zero,$\ ie,$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \oint_{}^{}\mathbf{B}.\mathbf{dA} = 0$
