Question

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

​​​​​​​$[$1 Mark$]$

• A. zero
• B. $\frac{{\mu }_0}{4\pi }$
• C. $4\pi {\mu }_0$
• D. $\frac{4{\mu }_0}{\pi }$

Answer 1

The correct option is A zero

The net magnetic flux through a closed surface, will be zero.
$\oint \overrightarrow{B}.d\overrightarrow{S}$ because there are no magnetic monopoles or magnetic field always form close loop.
