Michael Faraday
Michael Faraday was born in
Newington Butts, South London,
England, September 1791.
 He wasn’t from the richest family,
his father was a blacksmith and his
mother was the daughter of a
farmer, but he got basic education.
•At the age of 14 he left school to
become a book binder’s apprentice for over
seven years. During that period he
educated himself by reading books.
•In 1812 he went to 4 lectures of the
chemist Humphry Davy at the Royal
Institution, there he took notes of what
Humphrey was saying carefully, bound them
in leather and sent it to Davy with a job
application to be a his assistant, but Davy
had an assistant already.
•Later Davy hired Faraday as his assistant
because he fired the former one for
•Davy and Faraday went on a trip around
Europe where they met many other famous
chemists. He married Sarah Barnard, that
he met when attending a Sandemanian
•A Danish physicist Hans Christian Oersted
discovered that an electric current produced
a magnetic field. Since Faraday was back
•He built a device that included a hinged
wire, a chemical battery and a magnet.
When he turned on the current, a
magnetic field was set up in the wire, and
it began to spin around the magnet. The
electric current converted to magnetism.
Right then Faraday invented the electric
•Faraday then invented another device
called the Transformer. This device aimed
to convert magnetism back to electricity,
but it partially worked.
Faraday decided to reverse an experiment
done by Dominique Arago. Arago had
discovered that a rotating copper disk
diverted a magnetic needle. This was
magnetic induction. In 1831 Faraday took
a copper disk and spun it between the
poles of a permanent magnet. This set
up an electric current in the disk which
could be passed through a wire and put
to work, as long as the wheel spun,
current was produced. This experiment
produced tone of he greatest electrical
Faraday discovered the magnetic lines of
force," the compound benzene, how to
liquify various gasses, and the laws of
electrolysis. He developed the concept of
a field a force, magnetism, electric fields,
gravity that spreads throughout space and
is produced by magnets or electric
charge or, in the case of gravity, mass.
James Clerk Maxwell later developed his
famous equations describing
electromagnetism using this concept,
On August 25, 1867, Faraday died at
Hampton Court, Middlesex, England.
