There are at least two known locations on the Island that have electromagnetic anomalies in their vicinity: The Swan and The Orchid. Neither Maxwell’s fundamental differential equations on electromagnetism nor Einstein’s first papers considered the magnetic vector potential A. Hertz published his work in a book, "Electric Waves: Being Researches on the Propagation of Electric Action With Finite Velocity Through Space." Then in July 1820, Danish natural philosopher Hans Christian Oersted published a pamphlet that showed clearly that they were in fact closely related. Advancements in the Properties of Electromagnetism . The discovery of electromagnetic induction was made almost simultaneously, although independently, by Michael Faraday, who was first to make the discovery in 1831, and Joseph Henry in 1832. The famous mathematical equation formulated by Maxwell incorporated light and wave phenomena into electromagnetism. Henry had discovered electric induction quite independently in 1830, but his results were not published until after he had received news of Faraday’s 1831 work, nor did he develop the discovery as fully as Faraday. Contemporary historians of science do not all agree that the discovery of electromagnetism by Hans Christian Oersted in 1820 was directly tied to Friedrich Schelling's system of romantic nature philosophy, nor is it clear how one could establish this assertion beyond doubt. The Scotsman James Clerk Maxwell (1831–1879) is regarded as the greatest theoretical physicist of the 19th century. He had theoretically predicted electromagnetic waves. By the end of the 18th century, scientists had noticed many electrical phenomena and many magnetic phenomena, but most believed that these were distinct forces. Electromagnetism, a science of charge and of the forces and fields related to charge. Electromagnetism is one of the four fundamental interactions in nature. 546 B.C.E.

The DHARMA scientists, however, were using this pocket to conduct experiments in time travel. Humans knew there was a phenomenon, but it remained shrouded in mysticism until the 1600s when scientists began digging deeper into theory. Today, electromagnetism is used in many electric devices. French physicist Andre Marie Ampere (1775–1836) found that wires carrying current produce forces on each other, announcing his theory of electrodynamics in 1821. He was the first to say that positive and negative charges were regulated by one force. Thales discovered that amber rubbed with fur attracts bits of dust and hairs that create static electricity, and if he rubbed the amber for long enough, he could even get an electric spark to jump. Electromagnetism shows itself in many forms in day-to-day life and physics. The earliest writings about electromagnetism were in 600 BCE, when the ancient Greek philosopher, mathematician and scientist Thales of Miletus described his experiments rubbing animal fur on various substances such as amber.

Oersted and the Discovery of Electromagnetism by Frederick Gregory Department of History University of Florida. The electromagnetic attraction between atomic nuclei and their orbital electrons holds atoms together. Ampere's theory of electrodynamics states that two parallel portions of a circuit attract one another if the currents in them are flowing in the same direction, and repel one another if the currents flow in the opposite direction. Franklin also documented the conservation of charge, the theory that an isolated system has a constant total charge. The electromagnetic force usually produces electromagnetic fields, such as electric fields, magnetic fields and light. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. He reached that conclusion when he noticed that the compass needle get distracted when exposed to electric current. July 1820: Oersted & Electromagnetism. Two portions of circuits crossing one another obliquely attract one another if both the currents flow either towards or from the point of crossing and repel one another if one flows to and the other from that point.
