To solve this problem, we need to apply Gauss's law for magnetism.$\\$Gauss's law for magnetism states that the net magnetic flux $\Phi_B$ through any closed surface is zero.$\\$Mathematically, this is expressed as:$\\ \oint \mathbf{B} \cdot d\mathbf{A} = 0 \\$where $\mathbf{B}$ is the magnetic field vector and $d\mathbf{A}$ is the differential area vector on the closed surface.$\\$This law implies that magnetic monopoles do not exist, and magnetic field lines are continuous loops.$\\$Thus, the net magnetic flux through any closed surface is zero.$\\$Therefore, the correct option is:$\\$Option 1: Zero
