(1831-1879) James Clerk Maxwell was one of the greatest scientists of the nineteenth century. More generally, he predicted the existence of electromagnetic radiation: coupled electric and magnetic fields traveling as waves at a speed equal to the known speed of light. They relate the electric and magnetic fields to total charge and total current, including the complicated charges and currents in materials at the The term "Maxwell's equations" is often also used for The dynamically induced electric field has closed field lines similar to a magnetic field, unless superposed by a static (charge induced) electric field.

Do you have a question you'd like to ask regarding this article? The equations provide a mathematical model for electric, optical, and radio technologies, such as power generation, electric motors, wireless communication, lenses, radar etc. Already during Maxwell's lifetime, it was found that the known values for The above equations are the microscopic version of Maxwell's equations, expressing the electric and the magnetic fields in terms of the (possibly atomic-level) charges and currents present. For linear algebraic equations, one can make 'nice' rules to rewrite the equations and unknowns. The microscopic Maxwell equations have universal applicability but are unwieldy for common calculations. Ever since 1983 (see Further cosmetic changes, called rationalisations, are possible by absorbing factors of The equivalence of the differential and integral formulations are a consequence of the The integral version of Gauss's equation can thus be rewritten as
He also made significant contributions in the areas of physics, mathematics, astronomy and engineering. But in differential equations, and especially PDEs, one needs appropriate boundary conditions, which depend in not so obvious ways on the equations. On the other hand, the differential equations are purely Maxwell's equations can be formulated with possibly time-dependent surfaces and volumes by using the differential version and using Gauss and Stokes formula appropriately.

The concept of electromagnetic radiation originated with Maxwell, and his field equations, based on Michael Faraday ’s observations of the electric and magnetic lines of force, paved the way for Einstein’s special theory of relativity, which established the equivalence of mass and energy. This prompted several ‘copycat’ experiments from other physicists, all hoping to discover the fundamental nature of this mysterious connection.A decade after Oersted's experiment took place, Michael Faraday converted electric energy into magnetic energy using an insulated wire and a galvanometer. This aspect of Maxwell's addition to Ampère's law is particularly important: it makes the set of equations mathematically consistent for non static fields, without changing the laws of Ampere and Gauss for static fields.The speed calculated for electromagnetic waves, which could be predicted from experiments on charges and currents,In the electric and magnetic field formulation there are four equations that determine the fields for given charge and current distribution. Maxwell’s most significant scientific achievement was his electromagnetic theory of light propagation which he first presented in 1864 with the publication of An early inspiration for Maxwell's work took place in a Copenhagen in 1820, when Hans Christian Oersted embarked on a series of experiments in which he hoped to illustrate the connection between magnetism and electricity.
Maxwell’s new law and Faraday’s law couple together as a wave equation, implying that any disturbance in the electric and magnetic fields will travel out together in space at the speed of light … Pittcon. (accessed August 10, 2020).
