who established the close connection between electricity and magnetism
Hans Christian Ørsted Hans Christian Ørsted (/ˈɜːrstɛd/;[2] Danish: [hans kʁæsdjan ˈɶɐ̯sdɛð]; often rendered Oersted in English; 14 August 1777 – 9 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. He is still known today for Oersted's Law and the oersted (Oe), the cgs unit of magnetic H-field strength, is named after him. . He shaped post-Kantian philosophy and advances in science throughout the late 19th century.[3]
History of electric power transmission The first large scale hydroelectric generators in the USA were installed in 1895 at Niagara Falls and provided electricity to Buffalo, New York via power transmission lines. A statue of Nikola Tesla stands at Niagara Falls today in tribute to his contributions.
