Today (August 14, 1777) is the birthday of Hans Christian Oersted, who discovered that electricity can create magnetic fields.

Today (August 14, 1777) is the birthday of Hans Christian Oersted, who discovered that electricity can create magnetic fields.

Hans Christian Oersted was born on August 14, 1777 in Rutkabing. Young Asset developed an interest in science while working for his father, who owned a local pharmacy. He and his brother Anders received their early education through self-study at home. In 1793 they went to Copenhagen and took the entrance examinations at the University of Copenhagen. There the two brothers excelled academically. By 1796, Oersted was honored for his papers in both aesthetics and physics. In 1799 he received his doctorate in The Architectonics of Natural Metaphysics for a dissertation based on Kant's works.

In 1800, Alessandro Volta announced the discovery of his Voltaic pile. This encouraged Oersted to study the nature of electricity and to conduct his first electrical experiments. In 1801, Oersted received a travel grant and a general grant. It helped me to travel for three years across Europe. He toured science headquarters across the continent, including Berlin and Paris. In Germany Oersted met Johann Wilhelm Ritter. The physicist believed that there was a connection between electricity and magnetism. This idea made sense to Oersted as he subscribed to the Condian thought on the unity of nature. Oerstead's conversations with Ritter drew him to the study of physics. In 1806 he became a professor at the University of Copenhagen.

Continued research on electric currents and acoustics. Under his guidance, the university developed a comprehensive physics and chemistry program and established new laboratories. The best part of his study was the discovery that electricity plays an important role in electromagnetism, creating magnetic fields. Proud to be the first to distinguish aluminum from metal. He made aluminum by compressing aluminum chloride. In a study in 1825, Oersted noted that a metal similar to tin was obtained when anhydrous aluminum chloride reacted with a potassium alloy. Friedrich Wohler, a scientist who repeated his experiment, declared that the available metal was potassium, not aluminum.

On April 21, 1820, he published his discovery that a compass needle was deflected by a nearby current from the magnetic north. This confirms the direct relationship between electricity and magnetism. He had been searching for the connection between electricity and magnetism since 1818 and was greatly confused by the results he received. His initial explanation was that, like light and heat, magnetic effects propagate from all sides of a wire carrying electricity. Three months later, he began a more serious investigation. He then published his findings. This shows that an electric field creates a circular magnetic field when it flows through a wire. For his invention, the Royal Society of London awarded him the Oersted the Copley Medal in 1820. The French Academy awarded him 3,000 francs.

Oersted discoveries sparked more research on electrodynamics throughout the scientific community. French physicist Andre-Marie Amber embodied the development of a single mathematical formula to represent the magnetic forces between current mathematical conductors. Hans Christian Oersted died in Copenhagen on March 9, 1851, at the age of 73, after discovering that electricity had the potential to create magnetic fields. He was buried in the Assistance Cemetery.
