1, michael faraday (UK) discovered electromagnetic induction (183 1), and realized magnetic energy power generation. Details: michael faraday (A.D. 179 1 ~ A.D. 1867) was a British physicist and chemist. Born into a poor blacksmith family in Newington, Surrey. Only attended elementary school. 183 1 year, he made a key breakthrough in the force field and changed human civilization forever. 1865438+In May 2005, he returned to the Royal Institute to conduct chemical research under the guidance of David. 1824 1 was elected as a member of the royal society, 1825 was appointed as the laboratory director of the royal society in February, and 1833- 1862 was appointed as the chemistry professor of the royal society. 1846 was awarded the Renford Medal and the Royal Medal. 2. georg simon ohm (Germany)-Resistance Ohm is a German physicist, who put forward the famous Ohm's law in classical electromagnetic theory. In order to commemorate its important contribution, people take its name as a resistance unit. The name of ohm is also used in other physical and related technical contents, such as "ohmic contact", "ohmic sterilization" and "ohmmeter". 3. James Prescott Joule (UK)-James Prescott Joule (James Prescott Joule; 1818 65438+February 24th-1889 65438+1October1), a British physicist, was born in salford, a suburb of Manchester. Because of his contributions to heat, thermodynamics and electricity, the Royal Society awarded him the highest honor-the Kopre Medal. In order to commemorate him, later generations named the unit of energy or work "Joule" or "coke" for short; The first letter "J" of Joule's surname is used to mark the heat. 4. André-Marie Ampère (France)-André-Marie Ampère (André-Marie Ampère, 1775- 1836), a French chemist, made outstanding achievements in the research of electromagnetic action, and also made contributions in mathematics and physics. Ampere, the international unit of current, is named after its surname. Details: The most important achievement of Ampere is the research on electromagnetic action from 1820 to 1827. 1820 In July, after H.C. Oster published a paper on the magnetic effect of current, Ampere reported his experimental results: the electrified coil is similar to a magnet; On September 25, he reported that two current-carrying wires interact with each other, and parallel currents in the same direction attract each other, while parallel currents in the opposite direction repel each other; The attraction and repulsion between the two coils are also discussed. Through a series of classic and simple experiments, he realized that magnetism is produced by moving electricity. He used this view to explain the causes of geomagnetism and material magnetism. He put forward the hypothesis of molecular current: the current flows from one end of the molecule and is injected from the other end through the space around the molecule; The current of non-magnetized molecules is evenly and symmetrically distributed and does not show magnetism to the outside; When influenced by an external magnet or current, the symmetry is destroyed, showing macroscopic magnetism, and then the molecules are magnetized. With the rapid development of science today, Ampere's molecular current hypothesis [1] has real content and becomes an important basis for understanding the magnetism of matter. In order to further illustrate the interaction between currents, during the period of 182 1 ~ 1825, Ampere made four exquisite experiments on the interaction between currents, and based on these four experiments, the interaction force formula between two current elements was deduced. 1827, Ampere incorporated his research on electromagnetic phenomena into the book Mathematical Theory of Electrodynamics Phenomenon, which is an important classical treatise in the history of electromagnetism and has a far-reaching influence on the future development of electromagnetism. In order to commemorate the outstanding contribution of ampere in electricity, the unit ampere of current is named after his surname. He studied probability theory and integral partial differential equations, which showed his special talent in mathematics. He also did chemical research, and David realized the elements chlorine and iodine almost at the same time; Three years later than avogadro, avogadro's law was deduced. 5. Alessandro Giuseppe Antonio Anastacio Walter (Italy)-Italian physicist Alessandro Giuseppe Antonio Anastasi Walter (1February 74518-1March 5, 827). Later he was made an earl. 6. james watt (UK)-Power james watt (1736 65438+ 10/9-1865438+August 25th, 2009) was a famous British inventor and an important figure during the industrial revolution. Member of the Royal Society and foreign researcher of the French Academy of Sciences. He made a series of major improvements to the original prototype of the steam engine that had appeared at that time, and invented single-cylinder single-action and single-cylinder double-action steam engines, which improved the thermal efficiency and operational reliability of the steam engine and made outstanding contributions to the development of social productive forces at that time. He improved the steam engine and invented the barometer and power hammer. In order to commemorate him, the unit of measurement of power and radiation flux in the system is called watt, which is often represented by the symbol "W". His name will be etched in the history of mankind forever. Excerpt from Baidu Encyclopedia
