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)

zero

Answer 2

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.
