Faraday achievement

Today, I would like to share with you the knowledge of Faraday's achievements. if you happen to solve the problems you are facing, don't forget to follow this site and start now! What are Faraday's famous achievements? The most famous one knows. I don't know which ones. All I know is that he invented magnetoelectricity. Who is the father of world electricity? The father of world electricity is Faraday. Faraday made numerous achievements in electricity in his life. Faraday not only invented many machines related to electromagnetism, but also put forward the famous theory of alternating current. In 1831, based on his knowledge of electromechanics, Faraday successfully developed a machine that can generate electricity on its own, that is, a generator. Faraday is called the father of electrodynamics to commemorate Faraday's great contribution. " The life story of Faraday Michael MichaelFaraday,1791-1867 was the greatest experimental physicist in the field of electromagnetics in the 19th century. He was born in Newington, near London, on September 22, 1791, the son of a blacksmith. Because of his poor family, he only attended primary school for two years between the ages of 7 and 9. He was a newsboy at the age of 12 and an apprentice for binding books in a bookstore at the age of 13. He liked reading, took advantage of his conditions in the bookstore, read a lot of science books, and started to do some simple chemical experiments. In the autumn of 1812, Faraday had the opportunity to listen to four lectures by the famous chemist David, which aroused great interest in scientific research. He carefully arranged and illustrated David's speech and sent it to David, hoping that David would help him realize his wish for scientific research. In March 1813, David recommended Faraday to be his assistant experimenter at the Royal Academy Laboratory. In October 1813, Faraday followed David on an 18-month academic expedition to the European continent. During this period, he had the opportunity to visit the laboratories of scientists from various countries, made friends with Ampere, Galusack and other famous scientists, and learned about their scientific research methods. After returning to England, Faraday began independent research work, and published his first chemical paper in 1816, and several more later. In 1820, Oster discovered that the magnetic effect of electric current attracted the attention of the scientific community and promoted the development of science. The editor-in-chief of the British philosophical Yearbook in 1821 invited David to write an article commenting on the theoretical development of electromagnetism experiments since Oster's discovery. David gave the job to Faraday. In the process of collecting data, Faraday had a great enthusiasm for the study of electromagnetic phenomena and began to turn to the study of electromagnetism. He carefully analyzed the magnetic effect of electric current and thought that since electric current can produce magnetism, can magnetism produce electricity? in 1822, he wrote down his thought in his diary: "Magnetic energy is converted into electricity." He has carried out systematic research in this area. At first, he tried to use a strong magnet to get close to a closed wire or to use a strong current to generate current in another closed conductor. a large number of experiments failed. After ten years of failure and retrial, it did not succeed until August 29, 1831. He has done dozens of such experiments in succession. In his paper on November 24, 1831, he summarized the generation of induced currents into five categories: changing currents; changing magnetic fields; moving constant currents; moving magnetic fields; and conductors moving in the magnetic field. He pointed out that the induced current is related to the change of the original current, not to the original current itself. He compared this phenomenon to the electrostatic induction on the conductor and called it "electromagnetic induction". In order to explain the phenomenon of electromagnetic induction, Faraday once put forward the concept of "electric tension". Later, after considering various situations of electromagnetic induction, it is considered that the generation of induced current can be attributed to the conductor "cutting magnetic line of force". Twenty years after the phenomenon of electromagnetic induction was discovered, the law of electromagnetic induction was not obtained until 1851. From 1833 to 1834, Faraday derived the law of electrolysis from experiments, which was the earliest strong evidence of charge discontinuity. Another contribution of Faraday is to put forward the concept of field. He opposes the idea of super-distance action and assumes that there is a substance in the space around the charged body and magnet, which plays the role of transmitting electric and magnetic force. He calls this material electric field and magnetic field. In 1852, he introduced the concepts of power line (electric field line) and magnetic force line (magnetic induction line), and used iron powder to show the shape of the magnetic force line around the magnetic rod. The concept of field and the model of the line of force were a major breakthrough to the traditional concept at that time. Starting from the physical picture of short-range action, Faraday also foresees the volatility and non-transience of the propagation of electrical and magnetic actions. He wrote "some new ideas that should now be kept in the archives of the Royal Society" in a sealed letter to the Royal Society on March 12, 1832, which was not released until 1938. Faraday explained his new point of view in the letter. It shows Faraday's profound physical insight and profound physical thought. Faraday organized his experiments into the book "Electrical Experimental Research", in which more than 3,000 items were collected and his experiments and conclusions were described in detail. It is a valuable scientific literature. Faraday is a self-taught scientist who has worked hard on the scientific journey for more than half a century without seeking fame and fortune. In 1825, he was involved in smelting stainless steel and re-crowned glass with good refractive properties, and many companies and manufacturers paid a lot of money to hire Faraday as their technical consultant. Faced with 150000 pounds of wealth and unpaid learning, Faraday chose the latter. In 1851, Faraday was unanimously elected president of the Royal Society, and he firmly resigned from the post. He devoted himself to the cause of scientific research and lived in poverty all his life. He retired from the Royal College in 1855. He died in London on August 25, 1867. In accordance with his wish to be an ordinary Michael Faraday all his life, his body was buried in Haggert Cemetery. In memory of him, the unit of capacitance, Farah, was named after him. Selected from: physics teacher's Handbook What is Faraday's contribution? Before about 1830, Faraday was mainly a chemist, but he first began to study electricity and magnetism in 1821, which may have planted seeds, and made a great discovery ten years later. Faraday's first period of scientific activity ended in 1830, when he became an accomplished professional consultant in analytical chemistry and practice and, more importantly, earned an international reputation for his solid scientific achievements. These scientific achievements include the preparation of new carbon compounds, such as the quot; high carbon & quot; named by him or the modern quot; hexachloroethane & quot;CCI3.CC13 and tetrachloroethylene CCI2:CC12, as well as the study of gases for London lighting (Faraday's brother works in the department). The gas is heated with animal oil and stored in cylindrical cans, where it often leaves a liquid. Faraday analyzed the residual liquid very carefully and skillfully and found that it contained a component with a boiling point fixed at 80 ℃ and its macrocomponent was CH. This is benzene, which is one of the main pillars of organic chemistry. But when Faraday discovered benzene, he did not realize its later importance and certainly did not understand its strange molecular structure. These inventions and discoveries suggest that Faraday would also be considered an outstanding chemist if he had no other contributions. Faraday's greatest achievement was from 1830 to 1839, when he was a first-rate scientist who contributed to the discovery of modern electricity. In 1821 he studied the magnetic action of the current discovered by Oster and made a major discovery: the direction of the magnetic action is perpendicular to the direction of the current that produces the magnetic action. Faraday also made an electric motor that proved the rotation of the wire in a constant magnetic field. He even proved this rotation in the geomagnetic field. The experiment impressed him and his contemporaries. Faraday firmly believes that the relationship between electricity and magnetism must be popularized, and if an electric current can produce a magnetic field, a magnetic field must also produce an electric current. Faraday thought about it for ten years. He did many experiments and failed. It was not until the end of 1831 that he made a great breakthrough. He invented an electromagnetic current generator, which was the original generator. At this time, Faraday not only made a cross-era contribution, but also laid the foundation for the future power industry. A politician once asked Faraday what was the use of his invention. He replied: & quot; I don't know yet, but one day you will tax them. & quot; diamagnetism is another major discovery of Faraday. Many substances make their direction perpendicular to the magnetic line of force when they make a fine needle. And it is pushed away by the poles of the magnet, which is caused by a very weak force, which is much weaker than the force acting on iron in a magnetic field. This is a phenomenon worthy of careful study, and Faraday spent months studying it. Faraday contains some amazing new basic ideas in his essay "some thoughts on Ray Vibration". Eighteen years later, Maxwell established the electromagnetic theory of light, he said: & Professor quot; Faraday clearly put forward the concept of the propagation of transverse magnetic disturbance in his article "some ideas on Ray Vibration". His electromagnetic theory of light is essentially the same as what I began to propose in this article, except that in 1846 there was no experimental data that could be used to calculate the velocity of propagation. & quot; in the 1850s, Faraday's scientific ability was weakened. He was also afflicted with memory and declining memory. Although he can still do some experiments, he is not as fast as he used to be. He tried to find out the interaction between gravity and electricity, but the result was negative. But this exploration continues from Faraday Einstein to this day. Faraday made his last experiment in 1862, trying to discover the effect of the magnetic field on the light emitted by the light source placed in the magnetic field, but the result was negative because the instrument he used was not sensitive enough to detect this subtle effect. Thirty years later, when Zeeman, then a young man, was inspired by reading Faraday's experimental plan, he redid the experiment with more sophisticated instruments and discovered the Zeeman effect, which was one of the harbingers of the new atomic physics. What did Faraday find? Faraday is a British physicist, chemist and inventor, so what did Faraday find? The following is to learn what Faraday has found for you. I hope it will be helpful to you! & # 65532; what Faraday found? everyone will know what Faraday found. Faraday's electromagnetic induction phenomenon, and then Faraday's law of electromagnetic induction, he also discovered the Faraday effect, this phenomenon is also very important. Faraday has made great contributions to physical science, and his achievements are great. Faraday discovered electromagnetic induction, and he also discovered the Faraday effect. Everyone will know about the phenomenon of Faraday electromagnetic induction, because without the great phenomena discovered by Faraday and him, there would be no society as developed as we are today. Faraday discovered the phenomenon of electromagnetic induction, but for some people who have not been in contact with physics, they still do not understand it. In this way, Faraday discovered what can be extended to generate an electric current in the conductor when a part of the conductor in the closed circuit cuts the magnetic line of force in the magnetic field, a phenomenon called electromagnetic induction. Faraday effect, the phenomenon that the vibrating surface rotates when a linearly polarized beam propagates along the direction of the magnetic field in a uniform isotropic medium in a magnetic field. What Faraday found, one is Faraday electromagnetic induction, the other is Faraday effect. As a result of the phenomena he discovered, he also summed up many laws, that is, Faraday's law of electromagnetic induction. The magnitude of the induced electromotive force in any closed circuit is equal to the rate of change of the magnetic flux through the circuit. This is Faraday's law of electromagnetic induction. The significance of this law is that it is proved by experiments that mechanical work can be transformed into electromagnetic energy by electromagnetic induction. This law has also invented the basic theoretical basis of modern generators, and has also been applied in electrical technology. Faraday's achievements mainly include two aspects, one is electricity, the other is chemistry. In the field of electricity, he invented the unipolar motor in 1821; in 1831, after a series of significant experiments, he discovered the Faraday electromagnetic induction, which bears his name, which is arguably one of his greatest contributions. Faraday also established a new concept-the change of magnetic field to produce an electric field, and on this basis, invented the earliest generator. Challenge the tradition, through experiments to make human beings have a deeper understanding of the nature of electricity, and come to the conclusion that even if the sources of electricity are different, the result is the same. Faraday made achievements in chemistry. First, when he was David's assistant, Faraday did a lot of research on chlorine, and in 1833, after a large number of experiments, that is, after acting an electric current in the aqueous solution of sodium chloride, chlorine could be obtained. and two kinds of chlorine carbide were found. Second, the creation of some common chemical methods, but also invented the predecessor of Bunsen burner, a heating tool, so that it is widely used in the laboratory; third, the invention of many chemical substances; fourth, the law of electrolysis, the discovery of this law has played a positive role in the progress of chemistry. Faraday's contribution Faraday was born into a poor blacksmith family in England. because of his poor family, he could not receive a good education, but his father was a very kind and open-minded man. He taught Faraday to be a kind man and guide him to learn. With the guidance of his father, coupled with the fact that he is a child who loves to learn, he has been studying by himself while working in primary school. There is no opportunity to learn. There is Faraday. He does experiments by himself, and he listens to all kinds of relevant speeches. It is such a spirit that enabled him to seize the opportunity of success and made great contributions to the production and life of human society. Faraday's contribution can not be measured by any material, his research involves electricity, magnetism, electrochemistry and so on, invented the motor and generator, variable voltage technology and so on. During his tenure as David's assistant, he mainly engaged in chemical research and made some achievements, such as the production of chlorine and discovered two kinds of chlorine carbide, a common chemical benzene also discovered by Faraday. The most important contribution of Faraday is his achievements in electricity. The invention of generators and motors has brought great good news to mankind. The law of conservation of charge has solved many physical problems. The most important thing is the discovery of Faraday's electromagnetic induction. The magnetic effect of the Oster current caused Faraday's thinking. He thought: "since electric energy produces magnetism, why can't magnetism produce electricity?" In order to prove his conjecture, it took him 10 years, and finally paid off by using magnetism to generate electricity. At this moment, the whole world must cheer because large-scale power transmission is possible. Without Faraday, there would be no electricity, not to mention the advent of electrification.
