Question:

Gauss law in magnetism signifies that

Options:

Magnetic lines of force can pass through a closed surface

Net flux through closed surface is zero, monopole does not exist

Net flux is always μ0 times the net charge enclosed

There always exist a monopole

Correct Answer:

Net flux through closed surface is zero, monopole does not exist

Explanation:

Gauss’ law in magnetism is 

Magnetic flux (ΦB)Closed surface = 0

Gauss's law for magnetism is one of the four Maxwell's equations that underlie classical electrodynamics. It states that the magnetic field B has divergence equal to zero. It is equivalent to the statement that magnetic monopoles do not exist.
