The net magnetic flux through any closed surface is zero. Which of the following law encapsulates this statement.

Key : 1  Guass law in magnetism  $\oint Bds=0$ (Because monopoles  do not exist)
Key : 2  Guass law in electrostatics is  $\oint Eds=\frac{q}{{\epsilon }_0}$
Key : 3 Coulomb’s law in magnetism  $F=\frac{{\mu }_0}{4\pi }\frac{m_1{m}_2}{r^2}$
Key : 4  Coulomb’s law in electrostatics $F=\frac{1}{4\pi {\epsilon }_0}\frac{q_1{q}_2}{r^2}$
