Faraday`s law of induction


Michael Faraday :-

Born on 22nd September , 1791 to an English blacksmith , Michael Faraday is legendary for his many contributions to the field of science Electro- magnetic induction , electro- magnetic rotations , magneto- optical effects , diamagnetism and d theory are few of his many discoveries . It may be difficult to believe , but the discoverer of all these phenomenon had little formal education . At the tender age of fourteen years , he was apprenticed to a bookseller and bookbinder . But this apprenticeship turned out to be a blessing in disguise

as Faraday took to reading all the books brought to him for binding . He also attended lectures by Humphrey Davy , the great scientist and this turned out to be turning point in his life . In 1812 , he wrote to Davy enclosing his extensive notes that he had taken during the lectures . Impressed by the quality of the notes , the willingness to learn and also due to a conjecture of circumstances , Davy appointed Faraday as an assistant in research and lectures . Thus Davy became a mentor for the young Faraday and showed him the line that Faraday was to take up later in life

By 1820 , Faraday was doing research on his own and his s on chemistry were accepted by the Royal Society . Following this breakthrough , Faraday went on to show that magnets exert force on current carrying conductors and also discovered benzene- an important organic compound used frequently in industry . However , his growing fame soured his relationship with Davy who felt let down by the fact that he was not given any credit by Faraday . The last nail in the coffin of their relationship came when Faraday was elected to the Royal Society in 1824

His epic experiments on electromagnetic induction happened in 1831 when he showed that a changing magnetic field can induce an EMF whose magnitude is equal to the rate of change of the magnetic field . This discovery won him worldwide acclaim . His ingenious invention of the concept of magnetic field lines to better understand the nature of magnetic field was a wonderful concept which revolutionized the entire research on magnetism . Faraday was never a mathematician , he developed simpler ways of understanding physics and his laws on electro- magnetic induction were put into mathematical form later by Maxwell

His numerous other contributions to science include the first electrical generator , the correct and accurate laws of electrochemistry , behavior of light in magnetic field and the discovery of benzene which has been mentioned earlier . Despite all his achievements and unprecedented fame Faraday remained humble , modest and simple . He declined knighthood honorary degrees and only reluctantly agreed to receive a pension in his later years after retirement . He died of ill health on 25th August 1867 and was buried in the Sandemanian plot in the Highgate Cemetery

Laws of Electromagnetic Induction :-

Faraday performed certain experiments which led to the discovery of the laws of electromagnetic induction . To understand the laws properly , we must first look through these...
