life style of great scientist Michael Faraday .....!
Michael Faraday, who came from a very poor family, became one of the greatest scientists in history. His achievement was remarkable in a time when science was the preserve of people born into privileged families. The unit of electrical capacitance is named the farad in his honor, with the symbol F.
The faraday is a dimensionless unit of electric charge quantity, equal to approximately 6.02 x 10 23 electric charge carriers. This is equivalent to one mole , also known as Avogadro's constant .
Education and Early Life
Michael Faraday was born on September 22, 1791 in London, England, UK. He was the third child of James and Margaret Faraday. His father was a blacksmith who had poor health. Before marriage, his mother had been a servant. The family lived in a degree of poverty.
Michael Faraday attended a local school until he was 13, where he received a basic education. To earn money for the family he started working as a delivery boy for a bookshop. He worked hard and impressed his employer. After a year, he was promoted to become an apprentice bookbinder
Michael Faraday’s Scientific Achievements and Discoveries:
It would be easy fill a book with details of all of Faraday’s discoveries – in both chemistry and physics. It is not an accident that Albert Einstein used to keep photos of three scientists in his office: Isaac Newton, James Clerk Maxwell and Michael Faraday.
Funnily enough, although in Faraday’s lifetime people had started to use the word physicist, Faraday disliked the word and always described himself as a philosopher. 1821: Discovery of Electromagnetic Rotation
This is a glimpse of what would eventually develop into the electric motor, based on Hans Christian Oersted’s discovery that a wire carrying electric current has magnetic properties.
1823: Gas Liquefaction and Refrigeration
In 1802 John Dalton had stated his belief that all gases could be liquified by the use of low temperatures and/or high pressures. Faraday provided hard evidence for Dalton’s belief by applying pressure to liquefy chlorine gas and ammonia gas for the first time.
1825: Discovery of Benzene
Historically, benzene is one of the most important substances in chemistry, both in a practical sense – i.e. making new materials; and in a theoretical sense – i.e. understanding chemical bonding. Michael Faraday discovered benzene in the oily residue left behind from producing gas for lighting in London.
1831: Discovery of Electromagnetic Induction
Faraday discovered that a varying magnetic field causes electricity to flow in an electric circuit.
1834: Faraday’s Laws of Electrolysis
This is the science of understanding what happens at the interface of an electrode with an ionic substance. Electrochemistry is the science that has produced the Li ion batteries and metal hydride batteries capable of powering modern mobile technology. Faraday’s laws are vital to our understanding of electrode reactions.

MICHAEL FARADAY PPT..

  1. 1. Michael Faraday 22 sep 1791 – 25 aug 1867 By: B.RaGhaVenDer Goud, EEE-A, 3rd Year, J.B Institute of Eng.. and Technology.
  2. 2. Education and Early-Life  Born on 22 September, 1791 in Newington Butts, England, UK.  3rd child of James and Margaret Faraday.  Till 13 he received basic education.  At 14, he was apprenticed to a local bookbinder George Riebau and studied himself for next 7 years.  In 1813, “Humphry Davy” appointed him to the job of chemical assistant at the Royal Institution.
  3. 3. Faraday’s electromagnetic rotation apparatus. Electricity flows through the wires. The liquid in the cups is mercury, a good conductor of electricity. In the cup on the right, the metal wire continuously rotates around the central magnet as long as electric current is flowing through the circuit
  4. 4.  In 1802 John Dalton had stated his belief that all gases could be liquified by the use of low temperatures and/or high pressures.  Faraday provided hard evidence for Dalton’s belief by applying pressure to liquefy chlorine gas and ammonia gas for the first time.
  5. 5.  The mechanical pumps could transform a gas at room temperature into a liquid. The liquid could then be evaporated, cooling its surroundings and the resulting gas could be collected and compressed by a pump into a liquid again, then the whole cycle could be repeated. Showing that ammonia could be liquefied under pressure, then evaporated to cause cooling, led to commercial refrigeration
  6. 6. Refrigiration: LNG Refrigiration Cycle
  7. 7.  Michael Faraday discovered benzene in the oily residue left behind from producing gas for lighting in London. C₆H₆ A model of a benzene molecule.
  8. 8.  Varying Magnetic Field causes Electricity to flow in an electric circuit.  He shown that movement could be turned into electricity.  Rotation (kinetic energy) is converted into electricity using electromagnetic induction.
  9. 9. Faraday's experiment showing induction between coils of wire Liquid battery
  10. 10. World’s first Electric Generator For producing continuous (pure) DC voltage
  11. 11. Faraday stated two laws on the basis of his studies on electrolysis: 1. Faraday’s first law 2. Faraday’s second law:
  12. 12.  when an electrical conductor becomes charged, all of the extra charge sits on the outside of the conductor. This means that the extra charge does not appear on the inside of a room or cage made of metal.  Faraday cages can also create dead zones for mobile communications.
  13. 13. Here a car’s metal body is acting as a Faraday Cage, protecting the occupants from the electric discharge.
  14. 14.  This effect showes that a magnetic field causes the plane of light polarization to rotate.  It is the to link electromagnetism and light.  Described fully by equations in which established that light is an electromagnetic
  15. 15. Faraday effect
  16. 16.  Faraday discovered that all substances are diamagnetic.  Diamagnetism opposes the direction of an applied magnetic field.
  17. 17. For example, If you held the north pole of a magnet near a strongly diamagnetic substance, this substance would be pushed away by the magnet.
  18. 18. On Aug 25th Michael Faraday left for the heavenly abode at , Middlesex, England. at Highgate cemetery, London
