Description

Wikipedia:
Hans Christian Ørsted 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. Oersted's law and the oersted (Oe) are named after him.

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
Ørsted was elected a foreign member of the Royal Swedish Academy of Sciences in 1822 and a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849.

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:
Hans Christian Ørsted, bedre kendt som H.C. Ørsted (født 14. august 1777 i Rudkøbing, død 9. marts 1851 i København), var en dansk fysiker, kemiker og farmaceut.
Han konstruerede et piezometer og isolerede grundstoffet aluminium for første gang.

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.

Men det var vanskeligt for ham at forstå virkningens natur, og han udsatte derfor den nærmere undersøgelse, indtil han havde skaffet sig et kraftigt galvanisk batteri. Han genoptog derefter forsøgene i juli måned. 21. juli 1820 udsendte han en kort latinsk beretning om forsøgene. Kun fire kvartsider stor indeholder den dog en stor mængde forsøg, som viser, at her virkelig er tale om en vekselvirkning mellem de to naturkræfter, mens legemerne, der bærer dem, og omgivelserne er uden indflydelse.

Betydningen af Ørsteds opdagelse stod straks klar for alle sagkyndige, og den blev udgangspunkt for den række opdagelser, som knytte sig til André-Marie Ampères og François Aragos navne, og som 11 år senere afsluttedes ved Faradays opdagelse af induktionen. Og at samtiden følte, hvor meget den skyldte Ørsted, er der vidnesbyrd nok om, blandt andet også i de æresbevisninger, der vistes ham fra de forskelligste sider. Skønt det i høj grad var andre, der drog konsekvenserne af opdagelsen, skal det dog fremhæves, at Ørsted viste, at loven om aktion og reaktion finder anvendelse på elektromagnetismen; derimod lykkedes det ikke ham at påvise jordmagnetismens indflydelse på en elektrisk strøm, han sagde, at hans apparat var for svagt.

Senere fandt Ørsted ud af, at Gian Domenico Romagnosi opdagede elektromagnetismen allerede i 1802.

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.
