Biography of Michael Faraday:
Michael Faraday was an English scientist who contributed to the study of electromagnetism and electrochemistry. He was born on September 22, 1791, in Newington Butts, Surrey, England, and passed away on August 25, 1867, in Hampton Court, Middlesex, England. Faraday’s main discoveries include the principles underlying electromagnetic induction, diamagnetism, and electrolysis. He also invented electromagnetic rotary devices that formed the foundation of electric motor technology. Faraday’s work on the magnetic field around a conductor carrying a direct current established the concept of the electromagnetic field in physics. He discovered that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. Faraday’s contributions to science earned him numerous awards, including the Royal Medal, Copley Medal, Rumford Medal, and Albert Medal.

Brief biography of Michael Faraday:
Michael Faraday (1791–1867) was a British scientist who made significant contributions to the fields of electromagnetism and electrochemistry. Here is a brief biography of Michael Faraday:
Michael Faraday's Early Life:
Birth: Michael Faraday was born on September 22, 1791, in Newington Butts, a suburb of London, England.
Family Background: Faraday's family was not affluent, and he received only a basic formal education. His father was a blacksmith.
Apprenticeship and Early Career:
At the age of 14, Faraday became an apprentice to a local bookbinder, where he developed an interest in science by reading the books that came through the shop.
In 1812, he attended lectures by the chemist Humphry Davy at the Royal Institution. Faraday's meticulous notes caught the attention of Davy, leading to his employment as Davy's assistant.
Scientific Achievements of Michael Faraday:
1. Electromagnetic Induction:
Faraday's most famous discovery was electromagnetic induction, demonstrated in 1831. He found that a changing magnetic field induces an electromotive force (EMF) in a nearby conductor.
This discovery laid the foundation for the development of electric generators and transformers.
2. Laws of Electrolysis:
Faraday's work on electrolysis led to the formulation of Faraday's laws of electrolysis. These laws describe the quantitative relationships between the amount of substance produced during electrolysis and the amount of electric charge passed through the electrolyte.
3. Faraday Cage:
Faraday also investigated the phenomenon of shielding from electric fields. His work on the Faraday cage demonstrated that a conducting enclosure can protect its contents from external electric fields.
Royal Institution:
Faraday spent much of his career at the Royal Institution of Great Britain, where he conducted groundbreaking experiments and delivered influential lectures.
Later Life:
Faraday declined several honors, including a knighthood and the presidency of the Royal Society, due to his religious beliefs as a member of the Sandemanians, a Christian sect.
He retired from active research in the 1850s but continued to attend scientific events and mentor young scientists.
Death of Michael Faraday:
Michael Faraday passed away on August 25, 1867, at his home in Hampton Court.
Legacy:
Faraday's contributions to science had a profound impact on the development of electrical technology.
The unit of capacitance, the farad, is named in his honor.
Faraday's work laid the groundwork for later physicists, and his influence extended to the understanding of the nature of electricity and magnetism.
Michael Faraday's work not only transformed the field of physics but also played a crucial role in the practical applications of electricity that would shape the modern world.
