Question

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. $\frac{4{\mu }_0}{4\pi }$

Answer 1

Answer: (A)

The net magnetic flux through a closed surface will be zero, i.e. $\oint \vec{B}\cdot d\vec{s}=0$, because there are no magnetic monopoles.
