• Notes

  https://en.m.wikipedia.org/wiki/Edwin_Hall ______ From FindaGrave: Nobel Prize Laureate Scientist, Inventor. Working on his doctoral thesis in physics in 1879, he discovered that a magnetic field would skew equipotential lines in a current-carrying conductor. His development of a transverse electric field in a solid material such as wire carries an electric current and is placed in a magnetic field to the current. This principle was patented and became known as the "Hall effect" a discovery comparable to the greatest ever for how little was known about electricity at the time. Full details of his phenomenon invention was published in the American Journal of Science and in the Philosophical Magazine in 1880. He joined Harvard University, Massachusetts in 1895 and was appointed professor of physics, a post he held until his retirement in 1921. He continued his thermoelectric research at Harvard, where he also wrote numerous physics textbooks and laboratory manuals for world wide distribution. The Hall effect, is the primary circuit of an electronic ignition system used in magnetic field sensors, now made in millions and is the official standard for electrical resistance. More than a century after its discovery, he was awarded the Nobel Prize for physics in 1985. Bio by: John "J-Cat" Griffith
