Today (August 25, 1867) is the Memorial Day of Michael Faraday, the great experimenter of modern electromagnetic technology who invented the dynamo.

Today (August 25, 1867) is the Memorial Day of Michael Faraday, the great experimenter of modern electromagnetic technology who invented the dynamo.

Michael Faraday was born on September 22, 1791, in Newton's Butts, near present-day Elephant & Castle, south London. His family was very poor. His father, James Barade, was a blacksmith. Barade had to take care of his own education. At the age of 14, he joined George Ribo, a bookmaker and salesman, as an apprentice. During the seven years, he was with her, she had the opportunity to read many books. This developed his interest in science, especially electronics. In his twenties, Humphrey Davy, a renowned chemist, and physicist had the opportunity to listen to his lectures. Faraday sent Dave the notes he had written on these lectures.

Davey said he would take care of Baradei when the opportunity arose and advised him to continue his book-making business. Shortly afterward, Davey, who had lost his sight in an accident during a chemical test, hired Michael Baradei as his assistant. Later, when the then Laboratory Assistant at the Royal Society was fired, Davy transferred the job to Paradox. In the class-based society of the time, Barade was not considered a dreamer. From 1813 to 1815 Davy embarked on a long voyage across the continent of Europe. Faraday also took part in the trip as Davy's scientific assistant. Davey's wife, Jane Abris, refused to equate Faraday with him and treated him like a servant in return. Suffering from this, Barade decided to withdraw from the field of science altogether. Very soon, however, Faraday became famous in Davey as well.

Michael Faraday initially worked as Humphrey Davy's assistant. Faraday was particularly involved in the study of chlorine. He discovered two new chemical compounds chlorine and carbon. He also conducted the first rigorous experiment on the diffusion of gases. This is an event that John Dalton first pointed out. The significance of this event was fully expressed by Thomas Graham and Joseph Losmidt. Faraday liquefied many gases. Studied the alloys of eff. He also developed many new types of glasses for optical purposes. Faraday invented the early form of the Bunsen burner. It is in practical use as a convenient source of heat in scientific laboratories around the world. Faraday worked extensively in the field of chemistry, discovering chemicals such as benzene (which he called hydrogen bicarbonate) and liquid gases such as chlorine.

The liquefaction of gases helped to convert gases into liquids with very low boiling points and provided a more solid basis for the concept of molecular accumulation. In 1820, Faraday published the first set of cells made from carbon and chlorine, C2Cl6 and C2Cl4. And published his results the following year. Faraday proved the synthesis of chlorine chloride hydrate discovered by Humphrey Dave in 1810. Faraday is responsible for discovering the laws of electrolysis and for popularizing vocabularies such as positive, negative, electrode, and ion. Faraday is famous for his research on electricity and magnetism. His first recorded experiment was to create a Voltaic pile of seven coins, stacked together with seven pieces of disk zinc and six pieces of paper dissolved in salt water. With this pile, he mixed magnesium sulfate. Faraday's 1831 experiments prove one study.

In 1821, shortly after the discovery of the electromagnetic phenomenon by the Danish physicist and chemist Hans Christian, Davey and the British scientist William Hyde Wollaston attempted to design an electric motor. But failed in it. Faraday talked about the problem between the two. He developed two devices called "electromagnetic rotations". One of this created rotation or motion with a continuous orbit called a unipolar motor. It was created by the magnetic force of a circular rotation around a circle extending to a length of mercury where a magnet is placed. If the current is supplied by a chemical battery, the wire will then rotate around the magnet. These experiments and discoveries laid the foundation of modern electromagnetic technology.

In the excitement of this discovery, Faraday published the results arbitrarily without having to discuss his discovery with either Wollston or Davidon. The controversy within the Royal Society caused a rift in his relationship with Davy and Faraday may have been appointed for other activities to prevent him from engaging in electromagnetic research for many years. From his earliest discovery in 1821, Faraday continued his laboratory work. He developed the necessary experience by studying the electromagnetic properties of materials. In 1824, Faraday set up a study circle to examine whether a magnetic field could regulate the current in a current. But no such relationship has been proven by multiple phase tests. This experiment yielded similar results following similar work conducted by light and magnets three years ago.

In 1832 he completed a series of experiments to explore the fundamentals of electricity. Faraday used "static" batteries and "animal electricity" to produce the phenomenon of electrolysis gravity, electrolysis, and magnetism. Contrary to the scientific opinion of his time, various "types" of power illusions. Instead, Faraday proposed that there be only one "electricity". And variable estimates of magnitude and intensity (current and voltage) generated events in different groups. At the end of his research, Faraday proposed that the electromagnetic force conductor extended to the empty space. This idea was rejected by his fellow scientists and Faraday was not alive at the time to see that later scholars finally accepted his view on science. Sensing lines emanating from electric currents and magnets led to seeing electric and magnetic fields.

Faraday carried out various tests on the test road. In particular, he is more interested in the fields of electricity and magnetism. He continued to explore the effects of electricity. He explored what was there when the shock hit somewhere. He also discovered that when electricity is transmitted through a wire, the compass on the side turns and finds that electricity can be applied by the magnet as well. All of his studies were related to electricity and magnetism. He was considered the father of the electromagnet industry. He also made new inroads in the so-called electronics industry.

Faraday's conceptual model was important for the successful development of electromagnetic devices that dominated engineering and industry for the remainder of the 19th century. He has made significant contributions to the fields of electromagnetism and electrochemistry. Michael Faraday is considered one of the greatest scientists in world history. Some scientific historians refer to him as the greatest experimenter in the history of science. It is because of his efforts that electricity has evolved into something suitable for general use. Michael Bardet, who laid the foundations of electromagnetic technology, passed away on August 25, 1867, in Middlesex, England, at the age of 75.
