Electromagnetism, Maxwell

In the following, these qualitative statements are developed in a more rigorous fashion. The discussion begins with the classical foundation of electromagnetism. Maxwell s equations. Expressions for linear and non-linear... 

The Lorentz force coupled with the Ampere law and the Faraday law leads to the balance of electromagnetic momentum2 which involves the (divergence of) electromagnetic (Maxwell) stress. The isotropic limit of this stress is the electromagnetic pressure... 

James Clerk Maxwell, a friend and colleague of Professor Thomson s, worked to unite research into electricity and magnetism into a unified, consistent theory of electromagnetism (Maxwell, 1861, 1865), which was also studied by the Curie brothers... 

Maxwell s equation are the basis for the calculation of electromagnetic fields. An exact solution of these equations can be given only in special cases, so that numerical approximations are used. If the problem is two-dimensional, a considerable reduction of the computation expenditure can be obtained by the introduction of the magnetic vector potential A =VxB. With the assumption that all field variables are sinusoidal, the time dependence... 

The central equations of electromagnetic theory are elegantly written in the fonn of four coupled equations for the electric and magnetic fields. These are known as Maxwell s equations. In free space, these equations take the fonn ... 

In the previous sections we have described the interaction of the electromagnetic field with matter, that is, tlie way the material is affected by the presence of the field. But there is a second, reciprocal perspective the excitation of the material by the electromagnetic field generates a dipole (polarization) where none existed previously. Over a sample of finite size this dipole is macroscopic, and serves as a new source tenu in Maxwell s equations. For weak fields, the source tenu, P, is linear in the field strength. Thus,... 

In order to rmderstand how light can be controlled, we must first review some of tire basic properties of tire electromagnetic field [8], The electromagnetic tlieory of light is governed by tire equations of James Clerk Maxwell. The field phenomena in free space with no sources are described by tire basic set of relationships below ... 

The necessary boundary conditions required for E and //to satisfy Maxwell s equations give rise to tire well known wave equation for tire electromagnetic field ... 

Since a discharge is characterized by having a substantial population of charged species (electrons and ions), it responds to an applied electromagnetic field. The applied field moves electrons in one direction and positive ions in the opposite direction, in accordance with Maxwell s laws. 

All electromagnetic phenomena are governed by Maxwell s equations, and one of the consequences is that certain mathematical relationships can be determined when light encounters boundaries between media. Three important conclusions that result for ellipsometry are ... 

The connection between the molar polarization Pm and the molar refraction Rm is through Maxwell s theory of electromagnetism, according to which e = (at low-frequency fields). This is the basis for considering the molar refraction a measure of polarizability. 

James Clerk Maxwell is the one theoretical physicist between Isaac Newton and Albert Einstein of a stature comparable to theirs. Maxwell s contributions to science ranged over many areas, of which the two greatest were his creation of the electromagnetic the-oiy of light, and his work on molecular physics, gas theoiy, and statistical mechanics. He entered the scientific scene in the early 1850s, immediately after the principle of conseiwation of energy had been established. Its impact is seen everywhere in his work. 

From Faraday Maxwell gained a way of chinking from Thomson, the first mathematizations of Faraday s ideas and several groundbreaking connections to the concept of energy from Weber, the remarkable insight that the ratio of the two kinds of force, electrostatic and electromagnetic, somehow involves a velocity.

This result was experimentally discovered in the nineteenth century, but it could not be explained by Maxwells theory of electromagnetism. (James Clerk Maxwell was a Scottish physicist whose formulation of the laws of electricity and magnetism were...
