Michael Faraday Presentation Transcript

Slide 1 - Michael Faraday English physicist, chemist, founder of the electromagnetic field exercises Member of the Royal Society of London
Slide 2 - Michael Faraday (1791-1867) was born in London . He studied independently. In 1813 he became an assistant H. Davy (English chemist and physicist, one of the founders of electrochemistry) at the Royal Institution in London in 1825 - the director of the laboratory of the Royal Institute , succeeding G. Davy, in 1833-1862 - Professor of Chemistry .
Slide 3 - In 1821 Faraday first realized the rotation of the magnet around a conductor with a current and a current carrying conductor around the magnet , creating a laboratory model of the motor. In this experiment clearly revealed the connection between electrical and magnetic phenomena . It is no coincidence that in the same year, Faraday set myself goal is " to turn the magnetism into electricity ."
Slide 4 - In 1831 he discovered the phenomenon of electromagnetic induction - the occurrence of an electric current in a conductor when the magnetic flux through the wire loop. In subsequent years, the scientist studied in detail the discovery of the phenomenon and established the laws of electromagnetic induction , discovered (1835 ) extra- after closing and opening and established their direction .
Slide 5 - Using extensive experimental material , Faraday proved the identity of the then known forms of electricity , " animal " , " magnetic " , thermoelectricity , electricity generated by friction , galvanic electricity . The desire to clarify the nature of the electric current led him to experiment on the current passing through the solutions of acids , salts and alkalis .
Slide 6 - Faraday introduced the concept of mobility ( 1827) , a cathode , an anode , ions , electrolysis , electrolytes , electrodes (1834 ); invented voltmeter (1833 ) ; in 1845 he discovered diamagnetism , and in 1847 - paramagnetism .
Slide 7 - In Faraday's work on electromagnetism as important is the concept of field . He was the first in the 30 of the 19th century introduced the concept of the field , in 1845 used the term "magnetic field" , clearly formulated his concept in 1852 . According to Albert Einstein's opinion, the idea of the field was the original idea of Faraday , the most important discovery since Newton .
Slide 8 - For a description of the electrical and magnetic phenomena Faraday introduced the idea of ​​the electric and magnetic field lines , which he, however , any real thought . He also is the creator of the electromagnetic field exercises . In 1846, in " Thoughts on the radial oscillations of " Faraday expressed the idea of the electromagnetic nature of light .
Slide 9 - In 1837 , scientists discovered the effect of dielectrics on electric interaction ( the polarization of dielectrics ) and introduced the concept of the dielectric constant ; He suggested distributing electric and magnetic interaction through an intermediate medium
Slide 10 - In 1843 Faraday experimentally proved the law of conservation of electric charge . He came close to opening the law of conservation and transformation of energy , having stated in 1840 the idea of the unity of the forces of nature ( the various forms of energy ) and their mutual transformation .
Slide 11 - Michael Faraday was a popularizer of physics, in particular his widely known book “History of a Candle”, translated into almost all languages of the world.
