Hello everyone, I'm Devanand
welcome  you all, to my channel, Guiding Light
Today we will talk about
Michael Faradays's Scientific life
in last video, i have talked about Michael Faraday's early life
if you want to watch that video

Michael Faraday sir joined on 1st march 1813 as a assistant in Royal institute
Sir was so happy
that within one week, he learned almost everything
and his first job was
to extract sugar from sugar beet plant
to set up laboratory
and to clean apparatus
Once...
in 1813
when Michael sir was experimenting with chemical
then there was another explosion
and in that explosion
Michael Sir's hand got injured
But Michael Sir's enthusiasm have not diminished at all
Davy sir got shock on seeing this
and Davy sir started smiling
after that, looking at Michael Sir's enthusiasm Royal Institute appointed one tutor
And Davy sir thought Experimental skills
how to write journals
how to write scientific language
started tell about all these
and Michael sir was learning with interest
Humphry Davy sir was going to Europe for  scientific tour
Humphry davy sir asked Michael Sir
would you join me as a  scientific assistant
if you come with me on Europe trip
then you will get a chance to meet big scientist
you will get to learn about many new things
then Michael Sir told to Humphary sir
It's ok sir, I will join you
but what about my job?
don't worry about that, you come Europe trip with me
for time being, you leave the job
when trip will end, then again you can join Royal institute
then Michael sir did not any problem
Michael Sir laughed saying I will come you
but there was a problem
when trip was about to start
one servant was supposed to come with humpry sir
who was going to help  Davy Sir
to pick up luggage  or any other work
that servant was not able to come
so the problem was
Davy sir and his wife was with him
and their servant did not came
so Davy sir requested Michael Sir
Michael will you work like with us like a servant
Davy Sir Didn't want Michael Sir to act like a servant
but there was no option
and Davy sir told, as soon as we reach France
i will find someone there
So Michael sir said no problem sir, I am ready to work like servant
so now trip began
now Michael sir was afraid about
Michael sir never went out of London
and this Europe trip was for one and half year
so Michael sir was already little nervous
but with that one more problem was there
Davy sir's wife belonged to rich class
and she did not give Michael Sir the status of a gentleman at all
so Michael sir didn't liked that
but Michael sir did not had any problem
because Michael Sir was doing his work sincerely
when they all reached France
then Davy sir got one servant
but that servant was not suitable
he was not working properly
so Davy Sir did not kept servant
it means, Michael Sir had to work as servant in entire tour
When Davy sir was meeting scientist
that time Michael Sir was also with them
but other scientist in France
they had problem
why Michael is coming in between, why is he interfering..
Once when Davy sir and Scientist were having dinner
Michael sir also joined them
Other scientist directly told Davy sir
don't let him join
Davy sir told, no problem, he is my assistant, he will be with me
but they told, it doesn't looks good, that he joins us
Because of that Michael sir was served in another room
Michael did not have any problem in working
but he was having problem with treatment
once Michael sir was attaining some lectures of scientist
but problem was, those lectures were in french
and Michael sir did not know french
but there Michael sir met Ampere Sir
after that he felt very good
because Ampere was known as newton of electricity
so Faraday Sir was happy
after that tour ended and they came back
and told Davy sir, I want to join back my job
so he told ok you can join, and then again he joined back as assistant
their relation was good
not only as mentor, but Davy Sir used to behave as a friend
and Faraday sir had learnt many things from 
Davy sir
once Davy sir told Faraday sir
that I need your help
those days there was one problem in Britan
Coal mines worker used candle in mines
but in mines, some times methane gas used to leak
when methane gas combined with air
and when that combination comes in contact with flame
there was explosion
because of these explosion, many workers died
so this was a big problem
Davy sir thought
that we should find solution for this
so Davy sir told Michael sir
you help me in this project
so they both read that problem in detail
solution was, they made a lamp
that lamp used to protect flame from atmosphere
so because of this, there was no chances of explosion
so this development was very much beneficial for coal miner in Britan
because of this Faraday sir also got famous
Davy sir was so happy, that he told Michael sir that now you can do research
and now you can publish your own paper
after this incident
Michael Sir was known to people
and the industrialist
they used to call 
Michael sir
for small works
such as analysis of steel or iron
so Michael sir started working like this
and used to learn new new things
after some days
if there is any technical issues, court used to call Michael sir for advice
till 1819, Michael Sir's image was as a leading chemist
Davy sir got honorary professorship
so because of that William Brande was new chemistry professor in Royal institute
but inspite of that Devy sir used to
guide Michael sir in any experiment
in 1820, there was one famous experiment
one danish scientist, Hans Christian orsted
his experiment
if any magnetic compass
you keep near electric wire
and when current passes through electric wire
that time magnetic compass needle used to deflect
now interesting thing was
this needle was not able to push or pull
this used to rotate
in circular fashion
so this was very interesting thing
so now this experiment was getting famous in entire Europe
all scientist wanted to know
that when current is moving from wire
so needle rotates
Davy sir was also trying to find out
what Davy sir did
he recreated this experiment in Royal institute
and there was one scientific friend of Davy sir
william wolston
they both came lab of royal institute
and started working on these experiment
according to william wolston theory
current moves in spiral fashion from wire
and when current moves in spiral fashion
because of that current there is force on needle
and Davy sir supported it, and both did experiment
and according to wolston sir
if electric wire is brought under strong magnetic field
so that wire can rotate on its own axis
wolston sir and Davy sir tried hard that wire rotates on its own axis
but nothing happened
and that day Michael faraday sir was not there
next day when Michael Faraday sir came in Lab
then Michael Faraday sir came to know that Davy sir and wolston sir is doing something
experiment
but Faraday sir did not show much interest
Michael Faraday sir got married on 12th June 1821 with Sara Barnard
One day Richard phillips came to meet Michael Faraday sir
member of royal institute
he told Michael sir that one journal is coming, Annals of Philosophy
in that we have to publish everything about electromagnetism
he gave this work to Michael Faraday Sir
and this was too much work
he took this work in his hand
and all experiments on electromagnetism
Michael Faraday sir started reading everything in detail
and this results were published in all journals
but he was reading all these
he started reading orstad experiment with interest
and he started thinking, what is happening that needle is rotating
then he thought of doing this experiment again
on sep 1821, George Barnard, brother of his wife came
Michael sir took him to lab of royal institute
and told today we will do some experiment
he was thinking of doing Orstad experiment again
and find out its reason
he took one glass container
and pored hot wax into that container
and inserted magnetic bar into that glass
because as soon as wax will dry
magnet will fix into it
then sir took liquid mercury
and poured that into container
because liquid mercury is one liquid metal which passes electricity
sir increased level of liquid mercury
and placed the level in such a way that one end of the magnet should come up
then sir left the electric wire in it freely
and that wire was connected to battery
now sir was hoping
that he gets some success
as soon as sir switched on battery
and as the current went by electric wire
and the wire that was moving around the magnet
and wire started rotating continuously around magnet
seeing this, Faraday sir's happiness went to another level
and Faraday sir shouted loudly
there they go, there they go..
then he stopped that experiment and done it in reverse manner
and then what sir did, left the magnets free and fixed electric wire
and again same thing happened
again when current came into the wire
and now magnet was rotating freely
it means
when electric wire comes into magnetic field
wire will start rotating
this was the big invention
now sir's happiness became uncontrollable
he started dancing, and told George, finally I did it
Then to celebrate, Michael sir went to circus
Now next day
this electromagnetic discovery
he wanted to publish this paper
next month
Quarterly journal of science paper were to be published
means sir had only one month
and then Michael sir thought of meeting wolston sir
and will tell him, how this wire rotates around magnet
but during those days, Wolston sir was not in town
and sir did not had much time that he can wait
and sir had to publish that paper
so he published
in Quarterly journal of science
and when this paper got published
Davy sir read
and as soon as sir read
he felt very bad
because nowhere in that paper was thanks written to Wolston sir and Davy sir
means he did not gave credits
Although the theory of Wolston sir used to say
that wire will rotate on its own axis, after its arrival in the magnetic field
and michael sir had showed that
that electric wire rotates around magnet
but who was a supported of Davy sir and Wolston sir
they started taunting Faraday sir
that he has copied wolston sir's idea
and straight away Faraday Sir was accused of plagiarism
but sir used to say, no its my invention
i have discovered, but no one was ready to listen
and wherever sir used to go, everyone taunted
so Michael sir was very upset
so sir thought, I would break the contact with the society
he was very upset about it
then Michael sir wrote letter to Wolston sir
and apologized
sir I haven't done it intentionally
and I will apologize in next paper
but Wolston sir din not gave any specific answer
then Michael sir said to Wolston sir that I want to meet you
then Wolston sir said, ok you can come and meet me tomorrow
but what happened in that meeting, nowhere is mentioned about it
this invention got famous in whole world
and many scientist were studying about it
because of this invention, first electric motor was invented
now michael sir thought, he won't research about electricity, he will go towards chemsitry
in 1823, Michael sir showed to whole world
how to liquify chlorine gas
and this was very big invention in chemistry
after this, michael sir became very popular
and many people used to admire sir
but there were many who did not give value to Michael sir at all
one day it happened that people who loved Michael sir
they put Michael sir's name for the fellowship in Royal institute
Davy Sir at that time was the president of Royal institute
and he didn't want Michael Sir to get the fellowship anyway
now the problem was
that Davy sir could not bear it
so he came to Michael sir and told to take out his name from nomination
so Michael sir said, i haven't gave my name for nomination
my admirers gave my name
so Davy sir told tell them to take out your name
Michael sir told, no they won't do like that
So Humphry sir directly told that
ok will see what president does
so Michael sir told Davy sir
do what you like
I can't do anything
then..
January 1824
Michael sir got fellowship
everyone were congratulating Michael sir
but that day Michael sir's and Davy Sir's relation had broken
after that there relation was not same
and it hurt Michael sir a lot
but what Michael sir will do
Michael sir was doing his work
in 1825, again Michael sir did something new
and Michael sir discovered Benzene
now sir has got famous
but that time, Davy sir was not well
Davy sir was ill
and in 1829, Davy sir died, due to heart attack
because of that death, michael sir was upset
and Michael sir had stopped working for few days
and he used to stay depressed
there was one author, who wanted to write biography about Davy sir
and that author contacted Michael sir
and told do you have letters of Humpry Davy
Michael sir answered Yes Of Course I have
those letters I can never throw
those letters were always with me and will remain
those are memories of Sir
So he gave those letters to author
and told, keep it safe
these are priceless
After that Michael sir was promoted as director of laboratory
now Michael sir has started taking lectures
Sir started running evening classes in royal institute
due to this, the royal institute was also getting some funding
which was very good
so , Michael sir now loved taking lectures
so sir used to take evening classes for children
and whole day he used to prepare for that
then Michael sir came towards electricity
and in 1831, he did something that no one could think of
what was happening those days, scientist used to believe
that electricity is different and magnetism is different
then Michael sir took one ring
sir wounded one side of ring with wire
and same did on second side
and this side of wire was connected with battery
and second side was connected with galvanometer
so one wire was connected with battery
and another side was not connected to battery it was connected with galvanometer
now as soon as sir turned on the battery
so the first coil got current
and because of that coil, magnetic field was developed
and that magnetic field penetrate in second coil
and as soon as magnetic field got penetrate in second coil
because of magnetic field penetration
electricity was created even in the second coil
this invention clearly tells
if electricity produces magnetism
so magnetism also produces electricity
Michael sir got his name across the world due to this invention
but there was one more scientist
Joseph Henry
who performed same experiment in US
means the same experiment was going on at two places at the same time
But Michael sir had published this experiment earlier
that is why this patent came to Michael sir
and today it is known as Faraday law of electromagnetic induction
for this invention, he was awarded with Copley medal
And after some time, Michael sir also got a full time Professorship in Royal institute
now sir's research was going on in full fledged
then in 1833
sir invented law of electrolysis
today what we read law of electrolysis
cathode, anode, electrode
all this credit goes to michael sir
this means
1830's time was incredible for Michael Faraday sir
