Question

The net magnetic flux through any closed surface, kept in a magnetic field is​

Answer 1

Answer:

the net magnetic flux in close surface is zero

Answer 2

heya, buddy !!

➦The net magnetic flux through any closed surface, kept in a magnetic field is zero

We know that ,Magnetic flux through any closed surface is zero means magnetic mono pole do not exist.

∴ The Mathematically if S is a closed surface and ds⃗ represent any elementary surface the we have

∮sB⃗ ⋅dS⃗ =0

or in differential form

∇⋅B⃗ =0
