Gauss' law for electrostatics relates the electric flux through a closed surface to the enclosed charge: E d A = Q ₀ . Gauss' law for magnetism states that the net magnetic flux through any closed surface is zero: B d A = 0 . Faraday's law of induction relates the induced electric field along a closed loop to the rate of change of magnetic flux through the loop: E d l = - d _B dt . Ampere-Maxwell's law relates the magnetic field along a closed loop to the conduction current and the rate of change of electric flux (
