Electromagnetic is one branch of physics. It was concerned with magnetism produced by electric currents and with the interaction of electric and magnetic fields. Electromagnetism is defined the interaction between a magnetic field and an electric field. People use electromagnetic to transmit electricity to other place, to supply electricity form magnetic fields and to store and conserve energy. Electromagnet has components of strong interaction, weak interaction and gravitational. According to Hans Christian Ørsted that electricity and magnetism are linked. He proved that an electric current produces a magnetic field as it flows through a wire. His findings resulted in intensive research throughout the scientific community in electrodynamics. A French Physicist, François Arago, observed in 1820 that an electric current will orient unmagnified iron filings in a circle around the wire. Hans Christian Ørsted also influenced French physicist André-Marie Ampère's (1820) developments of a single mathematical form to represent the magnetic forces between current-carrying conductors. Ørsted's discovery also represented a major step toward a unified concept of energy. According to the observation of Michael Faraday, extended by James Clerk Maxwell, and partially reformulated by Oliver Heaviside and Heinrich Hertz, electromagnetic had far-reaching consequences, one of which was the understanding of the nature of light. Unlike what was proposed in Electromagnetism, light and other electromagnetic waves are at the present seen as taking the form of quantized, self-propagating oscillatory electromagnetic field disturbances which have been called photons. In 1802 Gian Domenico Romagnosi, an Italian legal scholar deflected a magnetic needle by electrostatic charges. Actually, no galvanic current existed in the setup and hence no electromagnetism was present. In another paper published Albert Einstein undermined the very foundations

    André-Marie Ampère, a French physicist and mathematician, founded electromagnetism, which he called electrodynamics. He was born in Lyon, France during the French Enlightenment, on January 20, 1775. His father, Jean-Jacques Ampère, and mother, Jeanne Antoinette Desutières-Sarcey Ampère, believed André’s education should be without formal schooling, and allowed him to teach himself with their library. When he was twelve, he was able to teach himself advanced mathematics because of his access to books.…

    The electromagnetic field (EMF) has been a natural part of the earth ever since the beginning of the universe and extends throughout all of space. It is a fundamental form of nature. The most familiar form of the electromagnetic field, to us, is found in sunlight. This electromagnetic field is actually the interaction of both an electric field, which is composed of stationary charges, and the magnetic field which consists of wave like currents.…

    The age-old Galilean relativity thereby met its end. Although the equations that Einstein derived to calculate coordinate transformations between reference frames had actually already been produced by Hendrik Lorentz, Lorentz had not considered the principle of relativity in his derivation; instead, Lorentz had set out to determine the coordinate differences between a moving observer and the absolute reference frame of the aether, the medium that he believed light propagated through. Einstein's theory resulted in the equations that Maxwell used to describe electromagnetism retaining their accuracy for all observers, but the new way of looking at the world that Einstein's theory provided gave far more gifts to the physics community. This grand reconstitution of physics was a major breakthrough for the field.…

    Maxwell demonstrated that electric and magnetic fields travel through space in the form of waves, and at the constant speed of light. Finally, in 1864 Maxwell wrote "A dynamical theory of the electromagnetic field", where he first proposed that light was in fact undulations in the same medium that is the cause of electric and magnetic phenomena.[3] His work in producing a unified model of electromagnetism is considered to be one of the greatest advances in physics.…

    Photoelectric Effect

    The photoelectric effect was not just an immediate discovery with a definite drawn conclusion. It involved many years of research, experimentation and debating. In 1887, Heinrich Hertz first discovered the concept of the photoelectric effect when he was investigating the production and reception of electromagnetic waves. From this experiment, after several years it was determined that when light shines on a metal surface, the surface emits electrons, for example, it can start a current in a circuit just by shining a light on a metal plate. In 1899, Joseph John Thompson investigated ultraviolet light in cathode ray tubes and deduced that cathode rays existed of negatively charged particles, which he called corpuscles (later called electrons). In 1901, Nikola Tesla received the patent US68597 (Apparatus for the Utilisation of Radiant Energy) that describes radiation charging and discharging conductors (metal plates) by "radiant energy". Tesla used this effect to charge a capacitator with energy by means of a conductive plate. These devices were referred to as "photoelectric alternating stepping motors". In 1905, Einstein published the theory that…
