Electromagnetism Home Electromagnetic Inertia Have you ever thought “If an electron induces a magnetic field when it moves, and magnetic fields contains energy, where does the energy to create this field come from?” Click here to find out more about Electromagnetic Inertia. Electrostatic Potential Energy The starting point for all electrostatic interactions is that between two point electric charges such as two electrons, or between a positron and an electron. In the 19th century scientists did not understand the interaction, and invented the concept of “potential energy” to provide the force that drove these particles together or apart. It was only when Einstein developed the equivalence of mass and energy that the true source of the energy became apparent. You are probably familiar with the concept that electric fields contain energy and it is the interaction between the fields of the two charges that leads to changes in their energy and hence to the forces between them, energy being simply the integral of force over distance. This paper develops the equations for the interaction at any point in space near the charges, without recourse to “potential energy”.

Electromagnetism From Wikipedia, the free encyclopedia. Electromagnetism Electricity Magnetism Electrostatics Electric charge ... Waveguides Quadrupole ("four-pole") magnet, focus particle beams in a particle accelerator . There are four steel pole tips, two opposing magnetic north poles and two opposing magnetic south poles. The steel is magnetized by a large electric current that flows in the coils of tubing wrapped around the poles. Electromagnetism is the physics of the electromagnetic field : a field , encompassing all of space, composed of the electric field and the magnetic field . The electric field can be produced by stationary electric charges , and gives rise to the electric force , which causes static electricity and drives the flow of electric current in electrical conductors . The magnetic field can be produced by the motion of electric charges, such as an electric current flowing along a wire, and gives rise to the magnetic force one associates with magnets . The term "electromagnetism" comes from the fact that the electric and magnetic fields are closely intertwined, and, under many circumstances, it is impossible to consider the two separately. For instance, a changing magnetic field gives rise to an electric field; this is the phenomenon of electromagnetic induction , which underlies the operation of electrical generators induction motors , and transformers . The term electrodynamics is sometimes used to refer to the combination of electromagnetism with mechanics . This subject deals with the effects of the electromagnetic field on the mechanical behavior of electrically charged particles.

Classical electromagnetism From Wikipedia, the free encyclopedia. Classical electromagnetism is a theory of electromagnetism that was developed over the course of the 19th century , most prominently by James Clerk Maxwell . It provides an excellent description of electromagnetic phenomena whenever the relevant length scales and field strengths are large enough that quantum mechanical effects are negligible. edit Lorentz force The electromagnetic field exerts the following force (often called the Lorentz force) on charged particles: where all boldfaced quantities are vectors F is the force that a charge q experiences, E is the electric field at q's location, v is q's velocity, B is the strength of the magnetic field at q's position. This description of the force between charged particles, unlike Coulomb's force law , does not break down under relativity and in fact, the magnetic force is seen as part of the relativistic interaction of fast moving charges that Coulomb's law neglects. edit The Electric Field E The electric field E is defined such that, on a stationary charge:
