Hans Christian Ørsted

Hans Christian Ørsted (14 August 1777 – 9 March 1851) was a Danish Physicist and chemist who is best known for discovering that electric currents can create magnetic fields,which is an important part of electromagnetism. He shaped post-Kantian phylosophy and advances in science throughout the late nineteenth century.He was also the first modern thinker to explicitly describe and name the thought experiment.

At the time of discovery, Ørsted did not suggest any satisfactory explanation of the phenomenon, nor did he try to represent the phenomenon in a mathematical framework. However, three months later he began more intensive investigations. Soon thereafter he published his findings, proving that an electric current produces a magnetic field as it flows through a wire. The CGS unit of Magnetic Induction (oersted) is named in honor of his contributions to the field of electromagnetism.

His findings resulted in intensive research throughout the scientific community in electrodynamics. The findings influenced French physicist Andre Maria Ampere's developments of a single mathematical form to represent the magnetic forces between current-carrying conductors. Ørsted's discovery also represented a major step toward a unified concept of energy.
