May be this should have been in math section but since this came out while studying Electrodynamics i put it here(adsbygoogle = window.adsbygoogle || []).push({});

we have

[tex]\boxed{\int_{S} \nabla \times \vec{B}.d\vec{a}=\oint \vec{B}.d\vec{l}}[/tex]

Q.well there are many areas with the same boundary which one to choose from?

well if we know the area the boundary is fixed but not vice-versa does only the right side equal left but nor always the left side equals right.

Can someone explain
