michael faraday was one of the most
influential contributors to modern
science and technology often referred to
as the father of electricity whose
outstanding discoveries observations and
experiments laid the foundations for
many inventions that we use today
he was born on 22nd of september 1791 in
surrey england and came from a very poor
family that belonged to a christian sect
named the sandomanians which according
to britannica was the single most
important influence on him and provided
spiritual sustenance throughout his life
at the age of 14 faraday was apprenticed
to a london book binder and here he
would spend lots of his time reading the
books that came into the store which led
him to develop a fascination for science
some sources say that faraday even began
conducting simple electrical experiments
during this time
he was presented with an opportunity to
take this further when one of the
customers kindly gave him a free ticket
to attend an upcoming lecture by sir
humphrey davey at the royal institution
after witnessing david speak faraday was
determined to find a way to work for him
and so he made a bound copy of all the
detailed notes he had taken during the
lecture and sent it to him along with a
letter asking for employment
despite his lack of formal education
davey appointed him laboratory assistant
and faraday immersed himself in the
study of chemistry becoming a skilled
analytical chemist in 1823 he discovered
that chlorine could be liquefied and in
1825 he discovered benzyne a key
substance in today's chemistry
in 1831 faraday focused his attention on
electricity and began a great series of
experiments that formed the basis of
modern electromagnetic technology one of
his first discoveries was
electromagnetic induction which led to
the creation of the first transformer he
began this experiment by creating his
famous induction ring which was two
separate lengths of wire wrapped around
opposite sides of an iron ring he then
connected one coil to a galvanometer
while connecting the other to a battery
as he connected and disconnected it he
noticed a galvanometer kick
this effect is now known as mutual
induction and forms the basis of all
transformers used today
in a second series of experiments in
september of that year faraday
discovered magnetoelectric induction the
production of a steady electric current
in other words the first electric
generator
faraday described these experiments in
two papers presented to the royal
society in which he gave his law of
electromagnetic induction
otherwise known as faraday's law
after reading this a young frenchman
hippolyte pixie took what faraday had
learned and developed upon it further by
creating his own version
and all generators in power stations
used today a direct descendants of the
machine he created with faraday's
principles
faraday continued his electrical
experiments and in 1832 he proved that
the electricity induced from a magnet
voltaic electricity produced by a
battery and static electricity were all
one and the same
he also laid the basis for
electrochemistry stating the first and
second laws of electrolysis
which plays an important role in modern
life
another outstanding example of faraday's
influence on modern technology is the
part he played in the invention of the
radio
in 1865 he helped james clerk maxwell
formulate an exact mathematical theory
of the propagation of electromagnetic
waves which laid the foundation of radio
communication
faraday was the greatest scientific
lecture of his time and considered it a
vital part of his position to educate
public on cutting-edge science when he
wasn't immersed within his experiments
he spent a lot of time publicizing the
great advances of the 19th century
science and technology through his
articles correspondence and the friday
evening discourses which he established
at the royal institution
he was also passionate about educating
youth and in 1825 at a time where
organized education for children was
scarce he established the royal
institution christmas lectures for
children
these were formed as an exciting new way
of presenting science to young people
and they are still taking place today
after over 50 years of service in 1865
faraday ended his connection with the
royal institution and two years later he
passed away at the age of 75
at his house in hampton court
his discoveries have had an incalculable
effect on subsequent scientific and
technical development he was a true
pioneer of scientific discovery
is a name of great significance in the
iet his statue stands outside savoy
place our london home and his name is
given to a major resource aimed at
getting young people into science and
engineering
we also hold an important collection of
his personal papers in the iet archives
but why is michael faraday so important
to the iet
after all he died four years before the
institution was formed
his journey from unqualified apprentice
to the most famous scientist of his day
his work on the fundamentals of physics
and electricity and his untiring efforts
to promote science and society have
ensured his legacy in history
faraday's story is one of how anybody
regardless of their education or
upbringing can make an impact on the
world and why it is crucial to share
your discoveries as you never know who
you may inspire
