 James Clerk Maxwell - Wikipedia, the free encyclopedia
Maxwell demonstrated that electric and magnetic forces are two complementary aspects of electromagnetism.
Maxwell's most important contribution was the extension and mathematical formulation of earlier work on electricity and magnetism by Michael Faraday, André-Marie Ampère, and others into a linked set of differential equations (originally, 20 equations in 20 variables, later re-expressed in quaternion and vector-based notations).
Furthermore, Maxwell showed that the equations predict waves of oscillating electric and magnetic fields that travel through empty space at a speed that could be predicted from simple electrical experiments—using the data available at the time, Maxwell obtained a velocity of 310,740,000 m/s.

The instrument is powered by a Ruhmkorff coil and connected to a pneumatic pump, and demonstrates the rotatory effect of a magnetic field on an electric discharge in a rarefied gas.
De La Rive's electric theory stated that the aurora, being influenced by the earth's magnetic field, would take place in the polar regions through processes of discharge between the positive electricity concentrated in the upper regions of the atmosphere and the negative electricity of the Earth.

Maxwell's' Treatise on Electricity and Magnetism (left) was first published in 1873.

The theory led the way for Hertz to confirm the existence of electromagnetic waves by producing them in his laboratory, and along with the quantum theory of Planck, initiated the present ideas on how radiant energy is propagated through space.

Instead, they agree that an electric current is a flow of "electricity." They also agree that electrons and protons carry charges of "electricity," and that quantities of electricity are to be measured in units of charge rather than units of energy.
Identity of Electricities," Faraday examines electric eels, examines the "static" from fur on rubber and from electrostatic generators, as well as the "current" from batteries and moving coils.
They replaced the term "Quantity of electricity" with "quantity of electric charge," then later shortened this to "quantity of charge." Scientists of today mostly use the term "electricity" as a chapter title, or to denote a whole class under which various phenomena are listed.

 Figures of Thought, by Thomas K. Simpson
James Clerk Maxwell’s Treatise on Electricity and Magnetism (1873) established the scope and the shape of classical electromagnetic science—from field theory (epitomized in “Maxwell’s equations”) to the electromagnetic theory of light.
The study consists of a careful reading of one crucial section of the Treatise, that in which Maxwell unfolds his "dynamical theory of the electromagnetic field"---namely, Chapters I through IX of Part iv.
To a very modest extent, it is a literary criticism, in the sense that it is concerned with the kind of question one would ordinarily expect to ask, for example, about a novel: questions of meaning, of structure, and of style.

Gooding's view of the relation of theory (roughly, a set of often only barely articulated assumptions about the structure and workings of the material world, assumptions that are often but not always mathematical) and practical experiment in scientific change is more synthetic.
Similarly, because a magnetic pole tends to move in a circle around a current-carrying wire, Faraday argued that both electricity and magnetism occurred as a result of movements in a medium, rather than as a result of changes in currents and magnets.
In his Treatise on Electricity and Magnetism (1861), James Clerk Maxwell wrote that Faraday "saw lines of force traversing all space where the mathematicians saw centers of force acting at a distance.

In Maxwell's "Treatise on Electricity and Magnetism", he expressed the hope that electromagnetism could be represented with quaternions someday.
Although equations for electricity and (possible) gravity are appearing in the same quaternion equation, they are not really unified.
One reason for the unification of electricity and magnetism can be seen by the complete cancellation of terms under the name of Faraday's law.

James Clerk Maxwell (13 June 1831 – 5 November 1879) was a Scottish mathematical physicist, born in Edinburgh.
He superintended every step of the progress of the building and of the purchase of the very valuable collection of apparatus with which it was equipped at the expense of its generous founder, the 7th Duke of Devonshire (chancellor of the university, and one of its most distinguished alumni).
Maxwell had married Katherine Mary Dewar when he was 27 years of age, but had fathered no children.
