---|---|
About 600 BC | Thales, who lived in Greece, studied attractive forces associated with magnets, and a resin called "amber."(see ref1) |
1600 | William Gilbert(1544-1603, British), wrote "De magnete". In this book, he explained why compass needle points north-south: the Earth itself is magnetic. |
1745 | Dutch physicist Pieter van Musschenbroek of the University of Leyden and Ewald Georg von Kleist of Pomerania invented the Leyden Jar.(see ref2) |
1747 | Benjamin Franklin (1706-90, American) realized there are two kind of charge: positive charge and negative charge and the law of charge conservation. |
1785 | Charles A. de Coulomb (French),Coulomb's Law . |
1799 | Alessandro Volta (Italian) Voltaic Cell invented the Voltaic Cell. |
1820 | Hans Christian Oersted(1777-1851) noticed an electric current produced a magnetic field. |
1820 | Andre Marie Ampere, Jean-Baptute Biot,and Felix Savart. |
1826 | Georg Simon Ohm (German) Established the Ohm's Law. |
1831 | Michael Faraday (British), pointed out electromagnetic induction in the production of electric current, by a change in magnetic intensity. |
1865 | James Maxwell (1831-1879, British), Maxwell Equation. |
1910 | Albert Einstein (1879-1955, German), theory of Relativity. |
