Gauss Law of Magnetism
Gauss’s Law of Magnetism states that the net magnetic flux through any closed surface is zero. Let’s say Magnetic Flux through an elemental area ΔA is given by ΔφB = B. ΔA then net Magnetic Flux is given as
φB = ∫ΔφB = ∫B. ΔA = 0
It means that the total number of magnetic field lines entering the surface is equal to the total number of lines exiting the surface.
Physical Significance of Gauss Law of Magnetism
The physical significance of Gauss law is that there is no source or sink of magnetic field lines, and isolated magnetic monopoles don’t exist i.e. even the smallest magnetic element consists of a dipole or a current loop.
Magnetic Flux
Magnetic Flux is defined as the surface integral of the normal component of the Magnetic Field(B) propagating through that surface. It is indicated by φ or φB. Its SI unit is Weber(Wb). The study of Magnetic Flux is done in Electromagnetism which is a branch of physics that deals with the relation between Electric Current and Magnetic Field.
