Maxwell Equations

Four Laws Maxwell’s equations in integral form are a set of FOUR LAWS resulting from several experimental findings and a purely mathematical contribution. Faraday’s Law Ampere’s Circuital Law Gauss’s Law for the Electrical Field Gauss’s Law for the Magnetic Field

Faraday’s Law The electromotive force around a closed path is equal to the time rate of change of the magnetic flux enclosed by the path

Ampere’s Circuital Law
The magnetomotive force around a closed path is equal to the algebraic sum of the current due to the flow of charges and the displacement current bounded by the path Displacement current introduced by Maxwell Current due to flow of free charges

Gauss’ Law for Electric Field
The displacement flux emanating from a closed surface is equal to the charge contained within the volume. The volume bounded by the surface S, Free charge Charge density

Gauss’ Law for Magnetic Field
The magnetic flux emanating from a closed surface is equal to zero Note that Gauss’ Law for magnetic field is consistent with Faraday’s Law

Law of Conservation of Charge
The net current due to flow of charge emanating from a closed surface is equal to the time rate of decreases of the charge within the volume bounded by the surface Gauss’ Law Ampere’s Law
