Question

The net magnetic flux through any closed surface, kept in a uniform magnetic field is?

• A. Zero
• B. $\frac{{\mu }_o}{4\pi }$
• C. $4\pi {\mu }_o$
• D. $\frac{4{\mu }_o}{\pi }$

Answer 1

The correct option is A Zero

The net magnetic flux through a closed surface is given by the Gauss law. The Gauss law is stated as follows:

$\varphi =\int B.dA$

And according to this law, the surface integral of the magnetic flux intensity over a closed surface is zero.

$\int B.dA=0$

So, option $\left(A\right)$ is correct.
