The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879. This is sometimes termed the ordinary Hall effect to … Visa mer The modern theory of electromagnetism was systematized by James Clerk Maxwell in the paper "On Physical Lines of Force", which was published in four parts between 1861 and 1862.
