In 1800, Alessandro Volta invented the voltaic pile, the first electrical battery. The following year, Oersted began to investigate the nature of electricity and to conduct his first electrical experiments. In 1820, while performing classroom demonstrations for his university students, Oersted passed electric current through a wire which caused a m...
Oersted’s discovery of electromagnetism unleashed a series of discoveries that eventually laid the foundation for our modern technology-enabled world. Soon after Oersted’s discovery, French physicist Andre-Marie Ampere developed a single mathematical formula to represent the magnetic forces that exist between current-carrying conductors. Then, over...
Oersted’s Law, named after Hans Oersted, is a law in electromagnetism that states that when a steady electric current passes through a wire it creates a magnetic field around it. Oersted’s Law is one of two laws that link electricity to magnetism, the other is Faraday’s Law of Induction. Oersted’s Law and Faraday’s Law later became part of the equa...
Hans Oersted had a pharmacological background and he also performed experiments in chemistry. In 1819, a year before he discovered electromagnetism, Oersted became the first person to discover the chemical compound Piperine. Piperine is a naturally occurring organic compound that is responsible for the pungency of black pepper and long pepper. Oers...
Aluminum is one of the most plentiful elements on earth. However, it is always combined with other elements. Many chemist thought that aluminum existed and there were numerous attempts to uncover it. However, it was Hans Oersted who became the first person to isolate aluminum in 1825. He reacted aluminum chloride (AlCl3) with potassium amalgam (an ...
A thought experiment is the act of reasoning through to the practical outcome of a hypothesis when physical proof is unavailable or unattainable. It involves asking the question “what if” and thenreasoning out the answer through a series of logical steps. Thought experiments were famously used by Albert Einstein to help him arrive at his theory of ...
In 1824, Oersted found the Society for the Dissemination of Natural Science, an organization dedicated to making science accessible to the public. The society still remains active and presents the H. C. Oersted Medal for scientific achievement. In 1829, Oersted also founded the College of Advanced Technology in Copenhagen, Denmark. It was Denmark’s...
In 1820, the British Royal Society awarded Oersted the Copley Medal, the greatest prize in science at the time, for his discovery of electromagnetism. In 1930, to commemorate Oersted’s contribution to electromagnetism and the impact it had on Physics as a discipline, the unit of theauxiliary magnetic field H in the CGS system of units was namedoers...
Oersted dived into the new science and, in 1801, published a scientific paper describing a new battery he had invented. He also described how to calculate the amount of electric current flowing by measuring the rate of gas production when electricity split water into hydrogen and oxygen.
Hans Christian Ørsted FRSE (/ ˈ ɜːr s t ɛ d /, Danish: [ˈhænˀs ˈkʰʁestjæn ˈɶɐ̯steð] ⓘ; often rendered Oersted in English; 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.

He wrote a short treatise on the discovery, but much of the important subsequent work relating to his finding was carried out by others, such as François Arago and André-Marie Ampère, the latter of whom made his greatest contribution to science by rigorously applying mathematics to the study of electromagnetism. 1820 was also the year that ...
Dec 5, 2015 · Additional Contributions to Science and Otherwise. In a multidisciplinary feat, Ørsted also discovered piperine, a component of pepper, in 1820 and was the first to isolate metallic aluminum in 1825. He also wrote many published essays, both philosophical and otherwise, in addition to poetic works.
When he was twelve, Hans began to help his father in the pharmacy, and the work stimulated his interest in science. In 1794 Oersted and his brother Anders matriculated at the University of Copenhagen. Hans studied the sciences, and Anders, who eventually became a leading jurist and a minister of state, studied law.
