Oster discovered the phenomenon of electromagnetic induction

Oersted discovered the phenomenon of the magnetic effect of electric current.

Explanation of the current magnetic effect:

The current magnetic effect refers to the phenomenon that any wire carrying current can produce a magnetic field around it. Magnetic phenomena and electrical phenomena were studied separately. In particular, Gilbert made an in-depth analysis and comparison of magnetic phenomena and electrical phenomena and concluded that electricity and magnetism are two completely different phenomena with little consistency.

Afterwards, many scientists believed that electricity and magnetism had no connection. Even Coulomb once asserted that electricity and magnetism are two completely different entities and they cannot interact or transform. But the question of whether there is a certain connection between electricity and magnetism has been lingering in the minds of some scientists who are interested in exploring.

Ampere’s law of current magnetic effects:

Oersted’s discovery caused a sensation throughout Europe, especially in the French academic world. The French physicist Arago listened to it in Switzerland When the news came that Oersted had discovered the magnetic effect of electric current, he felt the importance of this achievement very keenly, and immediately rushed back to France from Switzerland in early September 1820.

Oster's latest discovery was reported to the French Academy of Sciences on September 11. He described the experiment on the magnetic effect of current to his colleagues at the Academy in detail.

Oersted’s early life and middle life:

Oersted’s early life:

Hans Christian ?rsted (1777) August 14, 1851 – March 9, 1851), Danish physicist and chemist. Born on August 14, 1777 in Rudjobing, Langland Island, Denmark, into a family of pharmacists.

He started helping his father work in the pharmacy at the age of 12, while insisting on studying chemistry. Due to his hard work, he was admitted to the University of Copenhagen as a free student at the age of 17 with excellent results, studying medicine and natural sciences.

Oersted’s middle-aged experience:

From 1801 to 1803, he visited Germany, France and other countries and met many physicists and chemists. He served as professor of physics at the University of Copenhagen from 1806, and permanent secretary of the Royal Society of Denmark from 1815. In 1820, he was awarded the Copley Medal of the Royal Society for his outstanding discovery of the magnetic effect of electric current. From 1829 he served as dean of the Copenhagen Institute of Technology.
