The motor uses the principle that the energized conductor acts in the magnetic field (this is different from the magnetic effect of the current, the current ninth grade physics clearly separates the two), and the principle is found in Danish physics. Home - Oster, born on August 14, 1777, is a pharmacist family in Rud Jobin, Lang Lang Island. He was admitted to the University of Copenhagen in 1794 and received his Ph.D. in 1799. From 1801 to 1803, he visited Germany, France and other countries and met many physicists and chemists. He has been a professor of physics at the University of Copenhagen since 1806 and a permanent secretary of the Royal Society of Denmark since 1815. In 1820, he was awarded the Copley Medal by the Royal Society for his outstanding discovery of current magnetic effects.
Since 1829, he has served as Dean of the Copenhagen Institute of Technology. He died in Copenhagen on March 9, 1851. He has done research on physics, chemistry and philosophy. Influenced by Kant's philosophy and Schelling's natural philosophy, it is believed that the forces of nature can be transformed into each other and explore the connection between electricity and magnetism for a long time. In April 1820, the effect of current on the magnetic needle, the magnetic effect of the current, was finally discovered. On July 21 of the same year, he published his findings on the topic "Experiment on the role of magnetic needles in power conflicts." This short essay has caused great shock to the European physics community, leading to the emergence of a large number of experimental results, thus opening up a new field of physics - electromagnetics.
