Description | Wikipedia: Electromagnetism On 21 April 1820, during a lecture, Ørsted noticed a compass needle deflected from magnetic north when an electric current from a battery was switched on and off, confirming a direct relationship between electricity and magnetism. His initial interpretation was that magnetic effects radiate from all sides of a wire carrying an electric current, as do light and heat. Three months later he began more intensive investigations and soon thereafter published his findings, showing that an electric current produces a circular magnetic field as it flows through a wire. For his discovery, the Royal Society of London awarded Ørsted the Copley Medal in 1820 and the French Academy granted him 3,000 francs. Ørsted's findings stirred much research into electrodynamics throughout the scientific community, influencing French physicist André-Marie Ampère's developments of a single mathematical formula to represent the magnetic forces between current-carrying conductors. Ørsted's work also represented a major step toward a unified concept of energy. Later years He founded Selskabet for Naturlærens Udbredelse (SNU), a society to disseminate knowledge of the natural sciences, in 1824. He was also the founder of predecessor organizations which eventually became the Danish Meteorological Institute and the Danish Patent and Trademark Office. In 1829, Ørsted founded Den Polytekniske Læreanstalt ('College of Advanced Technology') which was later renamed the Technical University of Denmark (DTU). In 1825, Ørsted made a significant contribution to chemistry by producing aluminium for the first time. While an aluminium-iron alloy had previously been developed by Humphry Davy, Ørsted was the first to isolate the element via a reduction of aluminium chloride. Ørsted died in Copenhagen in 1851, aged 73, and was buried in the Assistens Cemetery.

Fra Wikipedia, den frie encyklopædi: Elektromagnetismen Angående denne opdagelse har Ørsted selv udtalt følgende: Under en række forelæsninger, han holdt i foråret 1820, blev tanken om sammenhængen mellem elektricitet og magnetisme særlig levende hos ham; han sendte da en stærk udladning gennem en fin platintråd og så virkelig, at en magnetnål, som befandt sig i nærheden, derved kom i bevægelse. Udstillingen I anledning af 200-året for H.C. Ørsteds opdagelse har H.C. Ørsted Selskabet med hjælp fra sponsorer og en række frivillige hjælpere etableret en udstilling om H.C. Ørsted, hans opdagelse og følgerne af denne. |
