Ampere is a French physicist. 1775 65438+1On October 22nd, Alex was born into a businessman's family in Bolimiyou, near Lyon, France.

The childhood memory of Ampere's powerful mathematical genius. Thinking deeply about Rousseau's education (17 12- 1778), my father decided to let Ampere teach himself and often took him to the library to read books. Ampere's history of teaching science, his book Encyclopedia. His favorite math, at the age of 13, he published the first math paper on spiral. 1799 ampere teaches mathematics in a middle school in Lyon. 1802 After leaving Lyon in February, he taught physics and chemistry at Fort College. In April, the Mathematical Theory of Gambling was published, which showed excellent mathematical skills and attracted attention from all walks of life. Later, Napoleon was created in the process of becoming a candidate for the French public school office. 1808 Ampere Police of Imperial University of France, 1809 Professor of Mathematics of Paris University. 18 14 was elected as an academician of the French academy of sciences. 1824—— He was appointed professor of experimental physics at the French Academy. He was elected as a member of the Royal Society in London 1827, England, and he is at the Stockholm Academy of Sciences in Berlin.

Ampere's main contribution to physics is an important discovery, the basic principles of electromagnetism, such as Ampere's law, Ampeton and molecular flow.

On July 2 1, 1820, Danish physicist Oster discovered the magnetic effect of current. Arago (1786- 1853), a French physicist who has long believed in Coulomb electricity and magnetism, responded quickly, saying that this great discovery was a great shock and had nothing to do with it. At the end of this month, in August, arago heard the news of Oster's success and immediately returned to France. On September 1 1, he gave a lecture on the details of Oster's experiment at the French Academy of Sciences. The next day, he repeated Oster's experiment, and on September 5, 2006, he published his first paper "Relationship and Current" in the journal Science of French Academy of Sciences. According to the research report of the Academy of Sciences on September 25th, as two parallel current-carrying wires, the second paper with the same direction attracts each other, and the currents of the two parallel current-carrying wires with opposite directions repel each other. 65438+1The third paper published on October 9th shows the bending shape with little interaction between various current-carrying wires. Later, Ampere did a lot of experiments, and used superb mathematical skills to sum up the power law between the current elements, the size and spacing of the two current elements to describe the interaction between the two current elements, and the relative direction. Later it was called Ampere's Law. On February 4th, 65438, the report of AMPS Academy of Sciences. Ampere is not satisfied with the results of these experimental studies. In 182 1 month, he put forward the famous molecular flow hypothesis, that is, the circle of each molecule is in the form of ten small magnets, which is the object of magnetic characteristics. The amplifier also compares the names of statics and dynamics. The first theory to study electrodynamics was called electrodynamics, which was published in' 1822 electrodynamics observation set' and 1827 electrodynamics theory. "In addition, Ampere also found that current flows in the coil.

Similar to magnetism and magnet performance, the first electromagnetic invention was created based on detection and quantity, and the electric millilitre was made for wearing training.

Ampere's research fields, such as philosophy and chemistry, even involve complex problems in plant taxonomy research. Special amplifier, thinking about the scientific problems of elephant cycle in this respect. Some people say that on one occasion, Ampei walked slowly to the school where he taught, thinking about Tuen Mun while walking. On the Seine, he picked up a pebble in his pocket. After a while, I took it out of my pocket and put it in the river. Shielding the school, he went into the classroom to dig pebbles in his pocket watch to see the time. It turned out that the pocket watch was thrown into the Seine. Another time: Ampere walked into the street and left. The problem with formula electricity is that it is not surprising to worry about operation. Suddenly, he saw the chalk on the blackboard in front and the operation on it. What becomes a "blackboard" is the storage space at the back of the falling car. Walking around the carriage, he followed, walking, writing, transporting, the faster-the faster, he ran over and finished his stop and buckle wholeheartedly until he caught up with the carriage. What is the effect of ampere on this disease? Pedestrians in the street laughed their heads off.

As the director of a university, he checked out 1836 amps. Unfortunately, he was infected with acute pneumonia and died in Marseille in June of 10 at the age of 6 1 year. In order to commemorate the ampere's current intensity unit, later generations called it "An" for short.

The current international unit of ampere, which is called a symbol for safety, is defined as: 1 m2, the distance between infinite parallel lines. When the constant current is equal, the force on each wire acts under a vacuum of 2× 10-7N, and the current on each wire is 1 amp.

The current has milliamperes, microamperes and other units.

1 A = 1000mA

Ma = 1000 microamperes.

The unit of battery mAH (milliampere hour) is the same as * * * *. For example, this 500MAH battery means that it can provide 500 mA× 1 hour = 1800 coulomb electrons, that is, it can provide an electrical appliance that consumes 500 mA to charge 1 hour.

Ampere (André-Marie Ampère 1775? 1836), a French physicist, also contributed to mathematics and chemistry. 177565438+1October 22nd, born in a wealthy family in Lyon. When they were young, their mathematical talent. He studied, and his father thought that Rousseau's educational philosophy provided a large number of books, which enabled him to learn independently and absorb nutrition. Rousseau's works on botany ignited his enthusiasm for science.

Scientific and technological achievements

1。 The main results of ampere electromagnetic interaction research range from 1820 to 1827.

① discover ampere's law

Oster's experiment of discovering the magnetic effect of current has aroused the belief that the relationship between Coulomb electricity and magnetism has great influence for a long time. He focused on our energy. After two weeks' report on the relationship between the direction of magnetic needle rotation and the direction of current and the right-handed rule, this group was named Ampere Rule.

(2) discover the law of current interaction

Then, he proposed that two parallel current-carrying conductors with the same current direction attract each other, while two parallel current-carrying conductors with opposite current directions repel each other. The attraction and repulsion between two coils are discussed.

③ The invented galvanometer

Ampere also discovered the performance of the magnetic field and magnet in which current flows in the coil, and created the first electromagnetic invention to detect and measure current, based on galvanometer.

④ The proposed molecular current hypothesis.

This view is based on the charge generated by magnetic motion to explain the reasons for geomagnetism and magnetic substances. The famous molecular current hypothesis. Amplifier constitutes the existence of ring current in magnet molecules-molecular current. The two magnetic poles of each magnetic molecule in the presence of molecular current are equivalent to forming a small magnet on both sides. Usually, the current direction of magnet molecules is chaotic, and the magnetic fields generated by them cancel each other, and there is no obvious external magnetic field. Under the external magnetic field, the current of molecular orientation is basically the same as that of adjacent molecules, but the surface part is not offset, and their effect is macroscopic magnetism. The unprovable molecular current hypothesis knows little about the structure of ampere materials and has quite a lot of speculative components. Today, molecules and molecules are made up of atoms. It is known that atoms' electrons move around the nucleus. Ampere molecular current hypothesis has real content and becomes an important basis for understanding the magnetism of materials.

⑤ The ampere's law, the legal function between current elements, is summarized.

Four complex experiments made by Ampere summarized the legal force between current elements and described the relationship between the interaction between two current elements and the size, spacing and relative direction of current elements. Later, people called this phenomenon Ampere's Law. The theoretical study of Ampere's motion is called electrodynamics. 1827 Ampere studied electromagnetic phenomena's mathematical theory of comprehensive electrodynamics in his book. It is a classic in the history of electromagnetism. In order to commemorate his outstanding contribution, the electromagnetic and current unit "Ampere" was named after his surname.

He also made many contributions in mathematics and chemistry. He studied probability theory and integral partial differential equations; ? David, who knows chlorine and iodine almost at the same time, derived Avon Gadereau constant, which was legally proved to be the relationship between volume and pressure at constant temperature, but he also tried to find the relationship between elements and the classification of orders.

3。 "electric Newton"

Ampere synthesized the mathematical theory of electrodynamics, and his research has become a classic work in the history of electromagnetism, which brought one of Ampere's most brilliant scientific achievements, Electric Newton, and Maxwell praised Ampere's work.

Later, it was said that the first person to measure electronic technology, automatic rotating magnetic needle to measure current amperage, or developed and improved galvanometer.

Amplifier has only been engaged in physics for a short time in his life, but he can be a unique and thorough person who analyzes and discusses the magnetic effect of charged conductors, so we call him the star of electrodynamics, and he is well deserved.

(Andrea Marie Ampere, 1775? 1836)

Ampere, French physicist. 177565438+1October 22nd, born in a wealthy family in Lyon. I received a good family education since I was a child. Educational thought, according to Rousseau's point of view, his father encouraged him to study by himself. /kloc-at the age of 0/2, he taught himself differential operation and various math books, showing a high-level mathematical talent. In order to be able to read the original Lyon library of Euler and Bernoulli's Latin, he spent several weeks mastering Latin. /kloc-at the age of 0/4, I studied the Encyclopedia, edited by Diderot and Darran Bell. He didn't go to any school. He learned all kinds of knowledge by self-study. Because his father was killed during the French Revolution 1793 (18 years old), in order to support his mentor. Rousseau read a book about botany and rekindled his enthusiasm for science. 1802, Professor of Physical Chemistry, Bourjean-Bryce Central School. 1808 was appointed as the new university * * *, and has been in this position ever since. 18 14 was elected as a member of the Department of Mathematics and Imperial College of the University. 18 19, presided over the philosophy lecture of the University of Paris. 1824 was appointed professor of experimental physics at the French Academy, and died in Marseilles on June 1836.

He has a wide interest in mathematics in his career. He studied probability theory and partial differential equations, as well as his mathematical papers. He is an opportunity that attracts D'Alembert. Later, in chemical research, it took him only three years to derive Biavo Garderot's constant as avogadro's law. Because of his superb mathematical skills, he became a pioneer of mathematical analysis in molecular physics. His research interests also include botany, optics, psychology, ethics, philosophy, science and classification. The analysis of AA natural classification written by him shows that Human Knowledge (1834 to 1843) is a comprehensive work involving subject knowledge.

His main scientific work is electromagnetism. 1820 oster discovered the magnetic effect of current. Arago returned to Paris, and he responded quickly. 1 month later, three papers reported the experimental results: the dynamic spiral steel pipe similar to a magnet, the interaction of two parallel long straight wires. His experiments prove that the earth's magnetic field is like a small needle-shaped directional solenoid valve. A series of experimental results gave him a clue: the current generated by the magnetic closure of the magnet. At first, he thought that there was a big magnetic current, but later he reminded his friends of Fresnel (magnet heat caused by current macroscopic circle) and put forward the molecular current hypothesis. He tried to quote Newton's mechanics and electromagnetism. He believes that the fundamental problem of electromagnetism and particles corresponding to current elements is to determine the interaction force between current elements. To this end, from 1820 to 10, he devoted himself to the study of the interaction between currents, during which his exquisite experimental techniques. Based on four typical experiments, he finally got the force formula between two current elements. His own theory is called "Mathematical Theory of Ampere Electromagnetic Electrodynamics, Main Works of Electrodynamics", which is one of the important classics of electromagnetism.

In addition, he also proposed that the magnetism of the electromagnetic soft core can be improved. 1820, he first proposed using electromagnetic phenomena to transmit telegraph signals.

Named after his surname Ampere, the unit of current intensity is one of the basic units of the International System of Units.
