The net magnetic flux through any closed surface is :
Answer: (A) Zero
Gauss's law for magnetism: $\displaystyle\oint\vec{B}\cdot d\vec{S} = 0$.
Magnetic monopoles do not exist, and magnetic field lines are closed loops. Every line that enters a closed surface also leaves it, so the net flux is zero.
