Hans Christian Ørsted (/ ˈ ɜːr s t ɛ d /; [5] Danish: [ˈhænˀs ˈkʰʁestjæn ˈɶɐ̯steð] ⓘ; anglicized as Oersted; [note 1] 14 August 1777 – 9 March 1851) 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 ...
The monument consists of a bronze statue of Ørsted mounted on a granite plinth. Ørsted is seen demonstrating the effect of an electric current on a magnetic needle. With his hands he is connecting the wires from an electric battery, thereby making a magnet oscillate.
In 1820, Hans Christian Ørsted discovered that electric currents exerted forces on magnets, while in 1831, Michael Faraday made the observation that time-varying magnetic fields could induce electric currents. Until then, electricity and magnetism had been thought of as unrelated phenomena.
Ørsted experiment (1820): Hans Christian Ørsted demonstrates the connection of electricity and magnetism by experiments involving a compass and electric circuits. Discovery of electromagnetic induction (1831): Michael Faraday discovers magnetic induction in an experiment with a closed ring of soft iron, with two windings of wire.
In 1820, Hans Christian Ørsted discovered a connection between electricity and magnetism, triggering decades of work that culminated in 1865, in James Clerk Maxwell's theory of electromagnetism, which achieved the second great unification in physics.
Hans Christian Ørsted. In the first half of the 19th century many very important additions were made to the world's knowledge concerning electricity and magnetism. For example, in 1820 Hans Christian Ørsted of Copenhagen discovered the deflecting effect of an electric current traversing a wire upon a suspended magnetic needle. [11]

In electromagnetism, Ørsted's law, also spelled Oersted's law, is the physical law stating that an electric current induces a magnetic field. [ 2 ] This was discovered on 21 April 1820 by Danish physicist Hans Christian Ørsted (1777–1851), [ 3 ] [ 4 ] when he noticed that the needle of a compass next to a wire carrying current turned so ...
