Equations best understood by starting with the maxwell equations and then adding to them the flavour of einsteins theory of relativity cf. Einsteinmaxwell equations encyclopedia of mathematics. The respect is well justified, since maxwell arguably came rather close to figuring out relativity decades before einstein. Introduction to einsteinmaxwell equations and the rainich conditions. Oersted in 1820, when he showed that an electric current in a wire can affect a compass needle.

Though he was published in scientific journals at 14 and venerated by albert einstein, james clerk maxwell s name isnt well known today. Maxwells equations in vacuo concrete5 ocean optics web book. The connection between electricity and magnetism and hence the term electromagnetism. The first results of einsteinmaxwell equations established by raincih in 1925 are therefore called the raincih conditions.

An essential guide to maxwells equations nova science. In this section we shall give a short discussion of einsteins equations of general. The equations provide a mathematical model for electric, optical, and radio technologies, such as power generation, electric motors, wireless communication, lenses, radar etc. These equations can be inserted into each other in the usual away to arrive at mostly uncoupled. In theoretical physics, hardly anything is better known than the einstein, maxwell and dirac equations. Maxwell s equations are a set of coupled partial differential equations that, together with the lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits. What problems with electromagnetism led einstein to the. Also, the authors present a generalization of these solutions to the nonlinear electrodynamics recently published in the literature. I think he might well have done so had he not died so young. Introduction the issue with maxwells equations physics. Einsteinmaxwell equations starting from a stationary vacuum metric. One of the consequences of maxwells equations is that they describe the existence of electromagnetic waves that propagate with a speed, c. Pdf superradiance of a charged scalar field coupled to.

It is well known through the work of majumdar, papapetrou, hartle, and hawking that the coupled einstein and maxwell equations admit a static mul. We are interested in solving the timeharmonic maxwell equations, which are obtained from their timedomain counterpart 2. We analyze the behavior of electromagnetic fields inside a resonant cavity by solving einsteinmaxwell field equations. Generating solutions to the einsteinmaxwell equations. The einsteinmaxwell em equations in a curved spacetime that admits at least one killing vector are derived, from a lagrangian. The many faces of maxwell, dirac and einstein equations. Inspired by the existence of such gravitational instantons in four dimensions and the wellknown methods to construct the higherdimensional convoluted solutions to the einsteinmaxwell theory, in this article, we construct and study new class of exact helicoidal and catenoidal solutions in einsteinmaxwell theory. As a simple example, we derive the kerrnewman solution.

This page begins a qualitative overview of maxwells equations. Relativity, maxwells equations of electromagnetism, and diracs equation of. Certainly maxwell s equations did far more than just hint at relativity. The science show takes a look at his life on the 150th. The einsteindiracmaxwell equations black hole solutions1 1. Maxwell equations article pdf available in journal of mathematical physics 1010. Charged cosmological dust solutions of the coupled einstein and maxwell equations joel spruck and yisong yang dedicated to louis nirenberg on the occasion of his 85th birthday abstract. Optimized schwarz methods for the timeharmonic maxwell.
