Hello, today we'll be talking about Michael
Faraday. About. Michael Faraday was a physicist
and chemist. He was born on September 22,
1791. He died on August 25, 1867 - when he
was 76 years old. He lived in England. Discoveries.
Michael Faraday was most famous for his contributions
to the understanding of electromagnetism.
He discovered electromagnetic rotation, Faraday's
cage, gas liquefaction. He discovered the
element benzene, he discovered two types of
chlorine and produced carbon. He also contributed
to the discovery of the electric generator.
These are three more discoveries that Michael
Faraday made. Electromagnetic induction, Faraday's
laws of electrolysis, and the Faraday effect.
These three discoveries will be what we'll
be talking about today. So what is electromagnetic
induction? Electricity can create magnetic
fields, so Faraday wondered if magnetic fields
could create electricity. And it can! You
can create electricity with changing, unstable
magnetic fields. A steady, stable magnetic
field does not produce any voltage. The uses
of this will have to do with the electric
generator, as I've said before. The movement
of this generator produces electricity with
electromagnetic induction. Faraday's laws
of electrolysis. Electrolysis is the channel
of electricity within electrolytes. Electrolytes
are liquid that conduct electricity. Faraday's
first law states that the quantity of chemical
variation is created by the current at electrode-electrolyte
boundary, which is relative to the amount
of electricity used. The second law states
that chemical change measure is created by the same electricity amount used
in a variety of substances proportional to
their equivalent weights. The Faraday effect.
The Faraday effect is the rotation of a plane
of polarization of a beam of light produced
by a magnetic field. This plane of polarization
is rotated when the light beam and the magnetic
field are parallel to each other. This happens
in a variety of substances varying from oxygen,
iron, nickel, and cobalt. The amount of rotation
depends on the strength of the magnetic field.
Early life. Michael Faraday had a very poor
and religious family. They believed in the
Sandemanians - a small part of Christian religion.
His father had major health issues so they
lived in a point of poverty. Faraday went
to school until he was thirteen years old
because he was whipped by his teacher. His
mother then decided that he was done with
public education. After this, he worked for
book delivery and then got promoted to bookbinding.
During this time, he discovered a fascination
with science when he read books here. When
he was done with this, he was apprentice to
Sir Humphrey Davy for learning all about chemistry.
Later life. Michael Faraday finally confirmed
the theory of the unity of forces. This theory
was a combination of all the forces and that
a force could be converted into another type
of force. This inspired James Maxwell who
created the electromagnetic field theory.
Faraday's mind started to fail in 1855. He
tried but failed to convert gravity into a
form of electricity. This has to go with the
unity of forces. After that, Queen Victoria
offered knighthood and a house. He was buried
in Highgate Cemetery, London - when he died.
