Unfortunately but fortunately, Faraday entered a bookstore as a bookbinder when he 14 years old, which gave him access to all kinds of books. Unlike ordinary young apprentices, Faraday loves reading. After busy work, he finds all the rest time and reads his bound books from beginning to end. Among them, the Encyclopedia Britannica and Madame Marcel's Chemical Dialogue have the greatest influence on him. This laid a good scientific foundation for his future research. In his spare time, he also made batteries out of empty bottles, tried various experiments and decided to become an academic researcher. Poor people can't be short-sighted!
Under the sponsorship of his brother, young Faraday often attended natural science lectures held by the Royal Academy of Sciences. Unlike most listeners, Faraday's notes are very detailed and neat. After listening, he copied his notes again and drew a diagram of the equipment. 18 12 years, Faraday listened to David's lectures four times. He was very interested, so he wrote down every word of the famous scholar, supplemented the content of the speech, and carefully bound his notes into a book called Sir Henry David's Lectures. This notebook, with beautiful calligraphy and exquisite illustrations, shows Faraday's meticulous and love for science. Before Christmas 18 12, he sent this beautiful note to David together with a letter of recommendation.
Faraday's efforts finally paid off. After receiving Faraday's gift and recommendation letter, David was moved by his concern and enthusiasm. Under the introduction of David, Faraday entered the royal college laboratory and became his assistant. Perhaps, David never thought that Faraday's achievements would far surpass him, and he was jealous of him afterwards. But David still regards Faraday's discovery as his most important achievement and is proud of it.
Ferrari finally jumped into the "Dragon Gate", and the rest should show their talents. After several years of dormancy, Faraday published his first scientific paper in 18 16, discussing the properties of quicklime, and made his mark in the scientific community. Shortly after learning that Oster discovered the magnetic effect of current, he found that the wire with current could rotate around the magnet and made the world's earliest motor, thus becoming one of the famous electricians.
Faraday has made numerous achievements in his scientific research career for more than 50 years. In the early years, hydrogen chloride, hydrogen sulfide and sulfur dioxide were liquefied successively, and the magnetic spin effect was discovered, and benzene was separated, each of which had far-reaching influence.
Of course, Faraday's most outstanding scientific contribution is the discovery of the concepts of electromagnetic induction and field. The discovery of the magnetic effect of electric current gave Faraday an idea with strong intuition: since electric current will produce a magnetic field, the reverse should also happen, that is to say, magnets can of course produce electricity. Electricity and magnetism should be a pair of harmonious and symmetrical phenomena.
After nearly ten years of repeated exploration and numerous failures, Faraday finally succeeded on August 26th 183 1. Like Oster, his success was "as easy as blowing off dust". Faraday did an experiment. He first wound a copper wire around an iron ring, connected an ammeter at both ends of the wire, and then inserted a magnetic bar in the coil. At the moment when the magnetic bar was inserted into the coil, Faraday noticed that the ammeter was slightly shaking. This shaking made Faraday full of joy-the magnetic force finally generated electricity.
This experiment not only confirmed the phenomenon of electromagnetic induction, but also realized the dream of "turning magnetism into electricity". On this basis, Faraday made the earliest generator. After that, with the successful manufacture of various motors and generators, large-scale production and application of electricity became possible, and human society began to move from "age of steam" to "electrification era".
On the basis of magnetoelectric induction experiment, he put forward the theory of electrostatic induction, and soon discovered diamagnetism, and introduced the concept of "field", which is the intermediate medium through which electricity and magnetism interact. The derivation of this concept, as Einstein said, is the most important discovery since Newton and Faraday's original thought.
After Faraday became famous, countries around the world awarded him as many as 94 honorary titles, but he said, "I admit that these honors are valuable, but I have never worked hard for them." He chose science as his goal in difficulties and hardships, persistently pursued truth, indifferent to fame and fortune, and upright and upright. He hid a steady stream of honors, certificates and awards on the bookshelf, and often lamented that the poor only had paper tombstones.
Faraday's life is simple and not luxurious. So that some people mistakenly think that he is an old janitor. In order to ensure his honesty and integrity, he repeatedly stressed that he was an ordinary person. He once politely refused the honor awarded to him by the Royal Society on the grounds that Faraday was born in a civilian and didn't want to be a nobleman. Faraday died on1August 25th, 867. According to his last wish, only his name and date of birth were engraved on the tombstone.
