• Unit 6: Maxwell's Equations

    Maxwell's four equations describe classical electromagnetism. James Clerk Maxwell, (1831–1879), the Scotish physicist, first published his classical theory of electromagnetism in his textbook, A Treatise on Electricity and Magnetism in 1873. His description of electromagnetism, which demonstrated that electricity and magnetism are different aspects of a unified electromagnetic field, holds true today. In fact, Maxwell's equations are consistent with relativity, which was not theorized until 30 years after he had completed his equations.
