Hellotoeveryone, we are Nyuma and Leti and
todaywewillexplainthelife of Michael Faraday and
playonone of hismostfamousinventions, thefirstelectric
motor.
3. Michael Faraday
He excelled in thehistory of science as a physicist and a
chemist. He wasconsideredone of
themostinfluentialscientist of all time. He wasbornon 22
September 1791 in Newington, Surrey, England.
Son of a blacksmith, had a poorchildhood. He
waseducated at Sandemanianmaintained by thesect,
whichfollowedthebiblicalbookofJob, emphasizing human
weakness.

4. In 1805, he leftschoolwith 13 yearsandwenttoLondon,
where he becameapprenticeofa bookbinderandbookseller.
In the store he found a
copyoftheEncyclopediaBritannicaandwithitsreadinghe
becamefascinatedby electricity.
In 1812, Sir Humphry Davy (from 1778 until 1829),
thefamousEnglishchemist, isworkingtemporarilyblindedin
hislaboratoryat the Royal Institute. A
customerofthebookstorerecommendedforFaraday
assistant. In 1813, with 21 years, Faraday assumedthe
post ofassistant.
5. In 1815, he becamesuperintendentofequipmentoftheRoyal
Institute in London. In thefollowingyears,
followstheworkoftheDanishphysicistHans Christian Orsted
(from 1777 until 1851),
andtheworkoftheFrenchphysicistAndre-Marie Ampere
(from 1775 until 1836). He buildshisownbatteries.
In 1821, he discoversthatelectricitycan produce a
rotatorymotion, theprincipleoftheelectricmotor. Constructs
a primitivemodelofengine. In 1823, he studies how gases
becomeliquidsat lowtemperatures. Liquefiedchlorine.
6. In 1824, he became a memberoftheRoyal
SocietyofLondon. In 1825,
workingwithAnalyticalChemistry. Faraday
discoveredbenzene. With 33 years, becomes director
ofthe Royal Institute.
In 1831, discoversthatelectricitycan be produced at one
time waspassingitby a magnet.

7. In 1841, with 50 years,
suffersfrompoorhealthandwenttolive in the country side. In
1845, he discoveredthata magneticfieldcan

nearLondon. In 1867, with 75 years, Faraday dies at
Hampton Courton August 25 andisburiedin
HighgateCemetery.
