Electromagnetism Electromagnetism is the combined study of electric and magnetic effects. moving charged particle produces a magnetic field A moving charged particle produces a magnetic field around itself. A current of moving charged particles produces a gg p p magnetic field around the current. Gian Domenico Romagnosi (1761-1835), an Italian philosopher, described electric current from a voltaic pile (an early type of battery) deflecting a magnetic needle in an Italian newspaper in 1802. Hans Christian Oersted (1777-1851), a Danish physicist and chemist, noticed that a compass needle deflected om the magnetic north when electric current from a October 13, 2009 Ch. 29: Magnetic Fields Due to Currents - Part A 2 from the magnetic north when electric current from a battery was switched on and off, 1820.

Electromagnetism Andre-Marie Ampere (1775-1836), a French physicist, extended Oersted’s work, one week after hearing about it, and developed the mathematical formula for the magnetic forces between current-carrying wires. Michael Faraday (1791-1867), a British physicist and emist discovered electromagnetic induction chemist, discovered electromagnetic induction – Faraday’s law, mutual induction, diamagnetism, laws of electrolysis, benzene, invented EM rotary devices,. .. Named after him: Faraday’s constant, the unit for capacitance Farad. mes Clerk Maxwell (1831 879) a Scottish James Clerk Maxwell (1831-1879), a Scottish theoretical physicist and mathematician; Maxwell’s equations – unified theory of electricity (1873), October 13, 2009 Ch. 29: Magnetic Fields Due to Currents - Part A 3 magnetism and EM waves, Maxwell-Boltzmann distribution, first color photograph.
