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.

André-Marie Ampère was a French physicist and mathematician who was one of the founders of classical electromagnetism. He established that electric currents produce magnetic fields and magnetic fields can produce electric currents. This laid the foundation for understanding the relationship between electricity and magnetism. The SI unit of electric current, the ampere, is named after Ampère in recognition of his contributions to establishing electromagnetism as a field of science.
1) Alessandro Volta was an Italian physicist born in 1745 in Como, Italy who made discoveries in electricity and invented the first battery, called the Voltaic Pile.
2) In 1775 he became a professor of physics and invented the electrophorus, a device that produced static electricity. He studied gases like hydrogen and methane.
3) In 1794, through experiments contacting two different metals, he discovered that this produced a small electrical response, which he called "contact electricity", leading to his invention of the first battery in 1800.
4) The Voltaic Pile battery consisted of discs of copper and zinc separated by cardboard soaked in salt water, producing electricity when the circuit was closed

Paulo Freire was a Brazilian philosopher and the father of critical pedagogy who developed the concept of conscientization. Conscientization is the ability to critically perceive the causes of social, political, and economic oppression in order to take action against oppressive elements of society. It involves developing a deep understanding of the world that leads to freedom from oppression. Freire viewed education as a tool for liberation that should involve dialogue between students and teachers to develop a shared critical understanding of reality. His educational philosophy emphasized problem-posing education, dialogue, and using education to promote conscientization and liberation.

A chemical bond is an attraction between atoms that allows the formation of substances containing two or more atoms. The bond is caused by electrostatic forces of attraction, either between electrons and nuclei or due to dipole attraction. When metals bond to nonmetals, electrons from the metal atoms are transferred to the nonmetal atoms, resulting in the metal atoms becoming positively charged ions and the nonmetal atoms becoming negatively charged ions.

2. Michael Faraday, (born September 22, 1791, Newington, Surrey, England—died August 25, 1867,
Hampton Court, Surrey), English physicist and chemist whose many experiments contributed greatly to
the understanding of electromagnetism.
Faraday, who became one of the greatest scientists of the 19th century, began his career as a chemist. He
wrote a manual of practical chemistry that reveals his mastery of the technical aspects of his art,
discovered a number of new organic compounds, among them benzene, and was the first to liquefy a
“permanent” gas (i.e., one that was believed to be incapable of liquefaction). His major contribution,
however, was in the field of electricity and magnetism. He was the first to produce an electric current
from a magnetic field, invented the first electric motor and dynamo, demonstrated the relation between
electricity and chemical bonding, discovered the effect of magnetism on light, and discovered and named
diamagnetism, the peculiar behaviour of certain substances in strong magnetic fields. He provided the
experimental, and a good deal of the theoretical, foundation upon which James Clerk Maxwell erected
classical electromagnetic field theory.
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 was eager to learn more about the world; he did not restrict himself to binding the shop’s
books. After working hard each day, he spent his free time reading the books he had bound.
Two books in particular captivated him:
The Encyclopedia Britannica – his source for electrical knowledge and much more
Conversations on Chemistry – 600 pages of chemistry for ordinary people written by Jane Marcet
Faraday’s education took another step upward when William Dance,a customer of the bookshop, asked if
he would like tickets to hear Sir Humphry Davy lecturing at the Royal Institution.
Sir Humphry Davy was one of the most famous scientists in the world. Faraday jumped at the chance and
attended four lectures about one of the newest problems in chemistry – defining acidity.
3. At this time Faraday had begun more sophisticated experiments at the back of the bookshop, building an
electric battery using copper coins and zinc discs separated by moist, salty paper. He used his battery to
decompose chemicals such as magnesium sulfate.
The article on electricity in the third edition of the Encyclopædia Britannica particularly fascinated him.
Using old bottles and lumber, he made a crude electrostatic generator and did simple experiments. He also
built a weak voltaic pile with which he performed experiments in electrochemistry.
Michael Faraday’s Career at the Royal
Institution
Faraday began work at the Royal Institution of Great Britain at the age of 21 on March 1, 1813.
He was destined to be associated with the Royal Institution for 54 years,ending up as a Professor of
Chemistry.
Faraday’s job as a chemical assistant was to prepare apparatus for the experiments and the lectures at the
Royal Institution.
At first, this involved working with nitrogen trichloride, the explosive which had already injured Davy.
Faraday himself was knocked unconscious briefly by another nitrogen chloride explosion, and then Davy
was injured again, finally (thankfully) putting to an end to work with that particular substance.
After just seven months at the Royal Institution, Davy took Faraday as his secretary on a tour of Europe
that lasted 18 months.
In 1816, aged 24, Faraday gave his first ever lecture, on the properties of matter, to the City Philosophical
Society. And he published his first ever academic paper, discussing his analysis of calcium hydroxide, in
the Quarterly Journal of Science.
In 1821, aged 29, he was promoted to be Superintendent of House and Laboratory of the Royal
Institution. He also married Sarah Barnard. He and his bride lived in rooms in the Royal Institution for
most of the next 46 years: no longer in attic rooms; they now lived in a comfortable suite Humphry Davy
himself had once lived in.
In 1824, aged 32, he was elected to the Royal Society. This was recognition that he had become a notable
scientist in his own right.
In 1825, aged 33, he became Director of the Royal Institution’s Laboratory.
4. In 1833, aged 41, he became Fullerian Professor of Chemistry at the Royal Institution of Great Britain. He
held this position for the rest of his life.
In 1848, aged 54, and again in 1858 he was offered the Presidency of the Royal Society, but he turned it
down.
Michael Faraday’s Scientific
Achievements and Discoveries
In Faraday’s lifetime people had started to use the word physicist, Faraday disliked the word and always
described himself as a philosopher.
He was a man devoted to discovery through experimentation, and he was famous for never giving up on
ideas which came from his scientific intuition.
If he thought an idea was a good one, he would keep experimenting through multiple failures until he got
what he expected; or until he finally decided that mother nature had shown his intuition to be wrong – but
in Faraday’s case,this was rare.
Here are some of his most notable discoveries:
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.
The Faraday Motor (The Homopolar Motor)
It has been argued that galaxies might behave like a device invented by Michael Faraday,the Homopolar
Motor. A Homopolar Motor is driven by magnetic fields induced in a circular, ridgid conductive metal
plate. The metal plate is placed between the poles of an electromagnet, causing it to spin at a steady rate
5. proportional to the input current. The meter attached to the wall in most backyards that determines
monthly electric bills is a Homopolar motor.
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.
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.
6. Showing that ammonia could be liquefied under pressure, then evaporated to
cause cooling, led to commercial refrigeration .
The ammonia liquefaction was of further interest, because Faraday observed that when he allowed the
ammonia to evaporate again, it caused cooling.The principle of cooling by artificial evaporation had been
demonstrated publicly by William Cullen in Edinburgh in 1756. Cullen had used a pump to reduce the
pressure above a flask of ether,causing the ether to evaporate quickly. The evaporation caused cooling,
and ice formed on the outside of the flask as moisture from the air came into contact with it.The
importance of Faraday’s discovery was that he had shown that 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. This is the basis of how modern refrigerators and freezers work.In 1862 Ferdinand Carré
demonstrated the world’s first commercial ice-making machine at the Universal London Exhibition. The
machine used ammonia as its coolant and produced ice at the rate of 200 kg per hour.
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
A model of a benzene molecule
7. 1831: Discovery of Electromagnetic
Induction
This was an enormously important discovery for the future of both science and technology. Faraday
discovered that a varying magnetic field causes electricity to flow in an electric circuit.
For example, moving a horseshoe magnet over a wire produces an electric current, because the movement
of the magnet causes a varying magnetic field.
Previously, people had only been able to produce electric current with a battery. Now Faraday had shown
that movement could be turned into electricity – or in more scientific language, kinetic energy could be
converted to electrical energy.
Most of the power in our homes today is produced using this principle. Rotation (kinetic energy) is
converted into electricity using electromagnetic induction. The rotation can be produced by high pressure
steam from coal, gas, or nuclear energy turning turbines; or by hydroelectric plants; or by wind-turbines,
for example.
1834: Faraday’s Laws of Electrolysis
Faraday was one of the major players in the founding of the new science of electrochemistry. 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:
Statements of the laws
Faraday's1st Law ofElectrolysis - "The mass of a substance altered at an electrode during
electrolysis is directly proportional to the quantity of electricity transferred at that electrode.
Quantity of electricity refers to the quantity of electrical charge,typically measured in coulomb."
Faraday's2ndLaw ofElectrolysis - "For a given quantity of D.C electricity (electric charge),
the mass of an elemental material altered at an electrode is directly proportional to the element's
equivalent weight". The equivalent weight of a substance is equal to its molar mass divided by the
change in oxidation state it undergoes upon electrolysis (often equal to its charge or valence).
8. Mathematical form
Faraday's laws can be summarized by
𝑚 = (
𝑄
𝐹
)(
𝑀
𝑧
)
where:
m is the mass of the substance liberated at an electrode in grams
Q is the total electric charge passed through the substance
F = 96485 C mol−1 is the Faraday constant
M is the molar mass of the substance
z is the valency number of ions of the substance (electrons transferred per ion).
Note that M/z is the same as the equivalent weight of the substance altered.
For Faraday's first law, M, F, and z are constants, so that the larger the value of Q the larger m
will be.
For Faraday's second law, Q, F, and z are constants,so that the larger the value of M/z
(equivalent weight) the larger m will be.
In the simple case of constant-current electrolysis, Q = I t leading to
𝑚 = (
𝐼𝑡
𝐹
)(
𝑀
𝑧
)
and then to
9. 𝑛 = (
𝐼𝑡
𝐹
)(
1
𝑧
﴿
where:
n is the amount of substance ("number of moles") liberated: n = m/M
t is the total time the constant current was applied.
In the more complicated case of a variable electric current, the total charge Q is the
electric currentI(τ) integrated over time τ)
𝑄 = ∫ (𝐼𝜏)𝑑𝜏
𝑡
𝑜
Here t is the total electrolysis time.
1836: Invention of the Faraday Cage
Faraday discovered that 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. In addition to offering protection for people, sensitive electrical or electrochemical
experiments can be placed inside a Faraday Cage to prevent interference from external electrical
activity.Faraday cages can also create dead zones for mobile communication
10. 1845: Discovery of the Faraday Effect – a
magneto-optical effect
This was another vital experiment in the history of science, the first to link electromagnetism and
light – a link finally described fully by James Clerk Maxwell’s equations in 1864, which established
that light is an electromagnetic wave.Faraday discovered that a magnetic field causes the plane of
light polarization to rotate.
11. 1845: Discovery of Diamagnetism as a
Property of all Matter
Faraday discovered that all substances are diamagnetic – most are weakly so – some are strongly
so.Diamagnetism opposes the direction of an applied magnetic field.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.Diamagnetism in materials, induced by very strong modern magnets, can be used to produce
levitation. Even living things, such as frogs, are diamagnetic – and can be levitated in a strong magnetic
field.
12. The Faraday Disc Generator
The purpose of these experimental investigations was to research,design & build a traditional two-piece
Faraday disc generator for physics demonstrations. The design is based on the models that follow Sir
Michael Faraday 's original 1831 disc dynamo very closely.
Faraday’s Books
Faraday's books, with the exception of Chemical Manipulation, were collections of scientific papers or
transcriptions of lectures. Since his death, Faraday's diary has been published, as have severallarge
volumes of his letters and Faraday's journal from his travels with Davy in 1813–1815.

Later life
13. In June 1832, the University of Oxford granted Faraday a Doctor of Civil Law degree (honorary). During
his lifetime, he was offered a knighthood in recognition for his services to science,which he turned down
on religious grounds, believing it was against the word of the Bible to accumulate riches and pursue
worldly reward,stating he preferred to remain "plain Mr Faraday to the end". He twice refused to become
President of the Royal Society.He was elected a foreign member of the Royal Swedish Academy of
Sciences in 1838, and was one of eight foreign members elected to the French Academy of Sciences in
1844. In 1849 he was elected as associated member to the Royal Institute of the Netherlands, which two
years later became the Royal Netherlands Academy of Arts and Sciences and he was subsequently made
foreign member.
Faraday died at his house at Hampton Court on 25 August 1867, aged 75.[25] He had previously turned
down burial in Westminster Abbey, but he has a memorial plaque there,near Isaac Newton's tomb.
Faraday was interred in the dissenters' (non-Anglican) section of Highgate Cemetery.
