MICHAEL FARADAY

He was not formally educated but he achieved success from what he created.

INTRODUCTION

• Michael Faraday was a most significant and prominent scientist in the history of world.
• His discoveries provides a lot knowledge about the thing that we are using nowadays.
• He was very hardworking.
• He devoted his precious life into the world of science from where he discovered and invented some most usable things.
• “man of god” this sentence fits very well on him.
• He didn’t thought he is a loser, he always thought he will achieve success one day.
• He is best known for his work on electricity and electrochemistry.
• Faraday proposed the law of electrolysis.
• He discovered benzene and other hydrocarbons.

ABOUT HIS PARENTS, FAMILY, SIBLINGS

• Michael Faraday mother’s name is Margaret Hastwell.
• Michael Faraday father’s name James Faraday.
• Michael Faraday wife’s name is Sarah Barnard.
• Michael Faraday siblings are Robert Faraday, Elizabeth Gary, Margaret Barnard, Richard Faraday and Thomas Faraday.

PERSONAL LIFE

• He was born on 22 September 1791 in Newington butts, which is now part of London borough of Southwark but was then a suburban part of Surrey.
• He was third child of his parents.
• He was a devote Christian.
• When he was 14 years old, he was apprenticed next seven years, educated himself by reading books on a wide range of scientific subjects.
• He had most basic school education to educate himself.
• He took more interest in science, especially in electricity.
• He was very inspired by the book of conversation on chemistry by Jane marcet.
• In 1812, when he 20 years old and at the end of his apprentice ship, he attended lectures by eminent English chemist Humphry Davy of the Royal institution and the Royal society and john tatum, founder of the city philosophical society.
• He sent Davy a 300 page book based on notes that he had taken during these lectures. Davy’s reply was immediate, kind and favourable.
• In 1813,when Davy damaged his eyesight in an accident with nitrogen trichloride, he decided to empty Faraday as an assistant.
• The Royal institution’s Jhon Payne had been asked Humphry Davy to find a replacement, thus he appointed Faraday as chemical assistant at Royal institution on 1 March 1813.
• Davy entrusted Faraday with the preparation of nitrogen trichloride samples, and they both were injured in an explosion of this very sensitive substance.
• Biographers have noted that “a strong sense of the unity of god are pervaded Faraday’s life and work.

INVENTIONS AND DISCOVERIES OF MICHEAL FARADAY

1. Electric motor – In 1821, set about trying to understand the work of orsted and ampere devising his own experiment using a small mercury bath. The device which converts electrical energy into mechanical energy, was the first electric motor.
2. Benzene – Benzene was first discovered by Faraday in 1825 in illuminating gas. Faraday did some experiments, and discovered that the new compound had equal numbers of carbons and hydrogens, and so named it ‘carbureted hydrogen’.
3. Electromagnetic induction-Faraday discovered electromagnetic induction on 29 August 1813. He found that, upon passing a current through one coil, a momentary current was induced in the other coil – mutual induction. If he moved a magnet through a loop of wire, an electric current flowed in that wire.
Laws of electromagnetic induction :-
(a) conductor is a closed circuit than the induced current flows through it. Whenever a conductor is placed in a varying magnetic field, EMF induces and this EMF is called an induced EMF and if the conductor circuits are closed current are also induced which is called induced current.
(b) The magnitude of the induced EMF is equal to the rate of change of flux linkages.
4. Electromagnetic generator – Michael Faraday also discovered a generator. This apparatus consists of a tube of neutral material wound with a coil of wire insulted in cotton, and a bar magnet. As the magnet moves the lines of magnetic force repeatedly intersect with the wire exciting
the electrons in the wire and generating electrical current.
5. Laws of electrolysis –
(a) First law of electrolysis is the amount of chemical change produced by current at an electrode electrolyte boundary is proportional to the quantity of electricity used
(b) Second law of electrolysis is The amounts of chemical changes produced by the same quantity of electricity in different substances are proportional to their equivalent weight.

Prizes and medals

❖ Royal medal (1835 and 1846)
❖ Copley medal (1832 and 1838)
❖ Rumford medal (1846)
❖ Albert medal (1866)

 Failures of Michael Faraday

Michael Faraday failed thousands of times and he has recorded all these failures. He wasn’t always so successful, he was asked to make glass. He tried for many months, but in the end was unsuccessful. He was son of a blacksmith and hated his job, but after time his patience paid off.

Quotes by Michael Faraday

▪ Nothing is to wonderful to be true if it be consistent with law of nature .
▪ There’s nothing I quite as frightening as someone who knows they are right.
▪ A man who is certain he is right is almost sure to be wrong.
▪ But still try, for who knows what is possible.
▪ I am not a poet, but if you think for yourselves, as l proceed, the facts will form a poem in your minds.
▪ I could trust a fact and always cross-question an assertion.
▪ The book of nature which we have to read is written by the fingers of God.
