Optional Unit VII: Electromagnetism B. Electromagnetism Key Concepts Oersted discovered that a magnetic field is created in the region of a current-carrying conductor. The direction of the magnetic field lines is dependent on the direction of current flow through a conductor. The magnetic field forms a series of concentric circles around a straight conductor. The strength of the magnetic field diminishes inversely as the radial distance from the conductor increases. At any given distance from the conductor, the strength of the magnetic field increases directly with the amount of current in the conductor. Ampere's Rule (right-hand rule) can be used to describe the direction of the magnetic field about a straight conductor. If the conductor is grasped with the right hand in such a way that the right thumb points in the direction of the current, the fingers wrap around the conductor in the direction of the magnetic field. (Some texts refer to the "right-hand rule". Avoid this convention to prevent unnecessary confusion.) The strength of a magnetic field around a conductor can be intensified by coiling the conductor into a loop. A large number of loops form a coil, or

55. Oersted, Hans (1777-1851) -- From Eric Weisstein's World Of Scientific Biography Short article about the discovery of electromagnetism. http://scienceworld.wolfram.com/biography/Oersted.html

Branch of Science Physicists Nationality Danish Oersted, Hans (1777-1851) Danish physicist and philosopher who, in 1819, discovered the deflection of a compass needle while performing a demonstration for his students. This discovery of a fundamental connection between electricity and magnetism rocked the scientific community and led to a flurry of activity in electrodynamic research by such investigators as and Arago . After all, the magnetism produced by a current would generate a force. Forces are capable of producing motion, so motion could come about which would lead to a current While this is not a conservation law, it is a statement about the fundamental interconvertibility of natural phenomena. It it is often stated that Oersted's was completely accidental and spontaneous. That contention is, however, misleading. Oersted had studied Naturphilosophie under Schelling himself, and wholeheartedly adopted the view that nature is systematic and unified. (He also thought that the practice of science is a religion.) The fact that he should be seeking a connection between electricity and magnetism was motivated entirely because of his prior philosophical conviction that one must exist. After all, only someone looking to find a connection between

Electric Charge electricity = phenomenon involving electric charges common examples are static electricity and lightening The existence of electricity , the phenomenon associated with stationary or moving electric charges, has been known since the Greeks discovered that amber, rubbed with fur, attracted light objects such as feathers. Ben Franklin proved the electrical nature of lightning (the famous key experiment) and also established the conventional use of negative and positive types of charges. Coulomb quantifies amount of charge and discovers force law between charges electrical force is similar to gravity in that it is inverse proportional to the square of the distance between charges charges are assigned positive or negative values like charges repel, opposites attract It was also known that certain materials blocked electric charge, called insulators, such as glass or cork. Other materials transfered electric charge with ease, called conductors, such as metal. By the 18th century, physicist Charles Coulomb defined the quantity of electricity later known as a coulomb, and determined the force law between electric charges, known as Coulomb's law. Coulomb's law is similar to the law of gravity in that the electrical force is inversely proportional to the distance of the charges squared, and proportional to the product of the charges. By the end of the 18th century, we had determined that electric charge could be stored in a conducting body if it is insulated from its surroundings. The first of these devices was the Leyden jar. consisted of a glass vial, partly filled with sheets of metal foil, the top of which was closed by a cork pierced with a wire or nail. To charge the jar, the exposed end of the wire is brought in contact with a friction device.

59. Electromagnetism electromagnetism Magnetism and electricity are not separate phenomena; they are the related manifestations of an underlying electromagnetic force. http://zebu.uoregon.edu/~js/glossary/electromagnetism.html

Electromagnetism Magnetism and electricity are not separate phenomena; they are the related manifestations of an underlying electromagnetic force. Experiments in the early 19th century by, among others, Hans Orsted (in Denmark), Andr-Marie Ampre (in France), and Michael Faraday (in England) revealed the intimate connection between electricity and magnetism and how the one can give rise to the other. The results of these experiments were synthesized in the 1850s by the Scottish physicist James Clerk Maxwell in his electromagnetic theory. Maxwell's theory predicted the existence of electromagnetic wavesundulations in intertwined electric and magnetic fields, traveling with the velocity of light.

60. James Clerk Maxwell The Scottish physicist James Clerk Maxwell (18311879) did revolutionary work in electromagnetism and the kinetic theory of gases. http://www.phy.hr/~dpaar/fizicari/xmaxwell.html

James Clerk Maxwell The Scottish physicist James Clerk Maxwell, b. Nov. 13, 1831, d. Nov. 5, 1879, did revolutionary work in electromagnetism and the kinetic theory of gases. After graduating (1854) with a degree in mathematics from Trinity College, Cambridge, he held professorships at Marischal College in Aberdeen (1856) and King's College in London (1860) and became the first Cavendish Professor of Physics at Cambridge in 1871. Maxwell's most important achievement was his extension and mathematical formulation of Michael Faraday's theories of electricity and magnetic lines of force. In his research, conducted between 1864 and 1873, Maxwell showed that a few relatively simple mathematical equations could express the behavior of electric and magnetic fields and their interrelated nature; that is, an oscillating electric charge produces an electromagnetic field. These four partial differential equations first appeared in fully developed form in Electricity and Magnetism (1873). Since known as Maxwell's equations they are one of the great achievements of 19th-century physics. Maxwell also calculated that the speed of propagation of an electromagnetic field is approximately that of the speed of light. He proposed that the phenomenon of light is therefore an electromagnetic phenomenon. Because charges can oscillate with any frequency, Maxwell concluded that visible light forms only a small part of the entire spectrum of possible electromagnetic radiation.
