1820: Oersted discovers link between electricity and magnetism Hans Christian Ørsted (Danish: [ˈɶɐ̯steð] ; 14 August 1777 – 9 March 1851), sometimes transliterated as Oersted ( UR-sted), was a Danish chemist and p hysicist who discovered that electric currents create magnetic fields. Why this milestone matters Breakthroughs in physics usually change how later scientists ask questions. This milestone shaped the tools, models, or experiments that came after it. Historical context: Oersted discovers link between electricity and magnetism Hans Christian Ørsted (Danish: [ˈɶɐ̯steð] ; 14 August 1777 – 9 March 1851), sometimes transliterated as Oersted ( UR-sted), was a Danish chemist and physicist who discovered that electric currents create magnetic fields. This phenomenon is known as Oersted's law. He also discovered aluminium, a chemical element. A leader of the Danish Golden Age, Ørsted was a close friend of Hans Christian Andersen and the brother of politician and jurist Anders Sandøe Ørsted, who served as Prime Minister of Denmark from 1853 to 1854.
