Gauss law for electricity

∮E⃗⋅dA⃗=Qϵ0\oint \vec E\cdot d\vec A=\frac{Q}{\epsilon_0}

Gauss law for magnetism

∮B⃗⋅dA⃗=0\oint \vec B\cdot d\vec A=0

Faraday law

∮E⃗⋅dl⃗=−dΦBdt\oint \vec E\cdot d\vec l=-\frac{d\Phi_B}{dt}

Ampere-Maxwell law

∮B⃗⋅dl⃗=μ0ic+μ0ϵ0dΦEdt\oint \vec B\cdot d\vec l=\mu_0 i_c+\mu_0\epsilon_0\frac{d\Phi_E}{dt}
