The story of British physicist and chemist Faraday, Michael? Faraday's successful story of discovering the law of electromagnetic induction tells us that ideals can only be realized by will and persistence. The following is the story of michael faraday that I carefully arranged for you. Welcome to read and learn!

brief introduction

1. 179 1 year, Faraday was born in a poor blacksmith's house in the suburbs of London. Father's income was meager, he was often ill and had many children. Faraday didn't even have enough to eat when he was a child. Sometimes he can only eat one loaf of bread a week, let alone go to school.

He especially likes books on electricity and mechanics. Faraday had no money to buy books, so he used waste paper from the printing house as a notebook, extracted all kinds of materials, and sometimes illustrated himself.

By chance, Dan, a member of the Royal Society of England, came to the printing factory to check his works and came across Faraday's? Manuscript? . When he knew that it was a note written by a bound apprentice, he was surprised, so Dance gave a lecture ticket to Faraday Royal College.

Faraday came to the Royal College with excitement. It was David who made this report, a famous English chemist at that time. Faraday stare big eyes, very attentively listening to David's lecture. After returning home, he compiled the lecture notes into a book as a chemistry textbook for self-study.

Later, Faraday sent his carefully bound chemistry textbook to Professor David with the letter, which said:? I am eager to escape from business and join the field of science, because according to my imagination, science can make people noble and amiable? .

David was deeply moved after receiving the letter. He admired Faraday's talent very much and decided to recruit him as his assistant. Faraday was very diligent and soon mastered the experimental technology and became David's right-hand man.

After half a year, David will make a scientific research trip to the European continent, visit famous scientists in European countries and visit chemical laboratories in various countries. David decided to take Faraday abroad. In this way, Faraday traveled in Europe with David for a year and a half, met famous scientists such as Ampere, gained a lot of knowledge and learned French.

After returning home, Faraday began to conduct independent scientific research. Soon, he discovered the phenomenon of electromagnetic induction. 1834, he discovered the law of electrolysis and shocked the scientific community. What is this law called? Faraday's law of electrolysis? .

7. Faraday, relying on hard self-study, stepped into the ranks of world-class scientists from an apprentice who had never attended primary school. Engels once praised Faraday as? The biggest electrician to date? .

8. 1867 On August 25th, Faraday died while sitting in his study, at the age of 76. Because of his great contribution to electrochemistry, people use his surname? Faraday? , which is the unit of electricity; Use the abbreviation of his last name.

The story of electromagnetic induction and Faraday

Our era is the era of electricity, but in fact we are sometimes called the space age and sometimes the atomic age, but no matter how far-reaching the significance of space travel and atomic weapons, they have relatively little impact on our daily lives. However, we have been using electrical appliances. In fact, no technical feature can completely penetrate the contemporary world like the use of electricity.

Many people have contributed to electricity, Charles? Augustine? Coulomb, Alessandro? Count the volts, Hans? Christian? Oster, Andrew? Mary? Ampere and others are the most important people. But far ahead of others are two great British scientists, Michael? Faraday and James? Clark. Maxwell. Although they are complementary to some extent, they are not partners. Their respective contributions are enough to put me at the top of this roster.

Michael. Faraday 179 1 was born in Newington, England. He was born in poverty and mainly relied on self-study. /kloc-When he was 0/4 years old, he was apprenticed to a man who installed and sold books, and took advantage of this opportunity to read widely. At the age of twenty, he listened to lectures by famous British scientists Humphrey and David, and became interested in it from then on. He wrote to David and finally got him a job as an assistant. Faraday made his great discovery a few years later. Although he has a poor foundation in mathematics, he is unparalleled as an experimental physicist.

182 1 year, Faraday completed the first major electrical invention. Two years ago, Oster discovered that if there is current in the circuit, the magnetic needle of the ordinary compass near it will shift. Faraday was inspired by this and thought that if the magnet was fixed, the coil might move. According to this idea, he successfully invented a simple device. In this device, as long as there is current passing through the wire, the wire will keep rotating around the magnet. In fact, Faraday invented the first motor, the first device to use electric current to move objects. Although this device is simple, it is the ancestor of all motors in the world today.

This is a major breakthrough. However, its practical use is still very limited, because there is no other way to generate electricity except simple batteries.

As we all know, a stationary magnet will not generate current in nearby lines. 183 1 Faraday found that when the first magnet passes through the closed circuit, there will be current in the circuit, and this effect is called electromagnetic induction. It is generally believed that Faraday's law of electromagnetic induction is one of his greatest contributions.

Two reasons are enough to show that this discovery can go down in history. First, Faraday's law is more important for understanding electromagnetism theoretically. Secondly, as Faraday demonstrated with his first generator (Faraday disk), electromagnetic induction can be used to generate continuous current. Although modern generators supplying power to towns and factories are much more complicated than those invented by Faraday, they are all made according to the same electromagnetic induction principle.

Faraday also contributed to chemistry. He invented the method of liquefying gas, discovered many chemical substances, including benzene, and more importantly, his contribution to electrochemistry (studying the chemical effects produced by electric current). After many detailed experiments, Faraday summed up two laws of electrolysis and named them after him, which formed the basis of electrochemistry. He gave popular names to many important terms in chemistry, such as anode, cathode, electrode and ion.

It was Faraday who introduced the two important concepts of magnetic field lines and wire strips into physics by emphasizing not the magnets themselves but the relationship between them? Field? This paved the way for many advances in contemporary physics, including Maxwell's equations. Faraday also found that if polarized light passes through a magnetic field, its polarization will change. This discovery is of special significance, indicating for the first time that there is a certain relationship between light and magnetism.

Faraday is not only clever but also handsome. He is a popular science lecturer, but he is modest and prudent, and takes fame, money and honor lightly. He refused to accept the knighthood granted to him, and also refused to accept the request that he be the president of the Royal Society. His married life is happy, harmonious and lasting, but he has no children. He died near London on 1867.
