What You'll Learn
Michael Faraday's early life
Michael Faraday, considered the "Father of Electricity", was born on September 22, 1791, in Newington, Surrey, now a part of South London. His father, James, was a blacksmith who had migrated from the north of England in search of work. His mother was a country woman who supported Faraday through a difficult childhood. The family belonged to a small Christian sect called Sandemanians, which provided spiritual sustenance to Faraday throughout his life and influenced how he interpreted nature.
Faraday received only basic schooling, learning to read, write, and cipher in a church Sunday school. At the age of 13, he worked as an errand boy for a bookbinding shop in London, where he read every book he bound and developed an interest in the concept of energy and, specifically, force. At 14, he became an apprentice to George Riebau, a local bookbinder and bookseller in Blandford Street. During his seven-year apprenticeship, Faraday read many books, including Isaac Watts's "The Improvement of the Mind", which inspired him to join discussions with his peers in the City Philosophical Society. He also attended lectures on various scientific topics, sparking his interest in science, especially electricity.
Faraday's early exposure to scientific books and his discussions with peers fuelled his passion for learning. He was particularly inspired by the book "Conversations on Chemistry" by Jane Marcet. In 1812, at the age of 20, he attended lectures by eminent English chemist Humphry Davy of the Royal Institution and the Royal Society. Faraday's interest in science eventually led him to become Davy's laboratory assistant, allowing him to learn from one of the greatest chemists of his time.
Faraday's curiosity and dedication to the pursuit of knowledge are evident in his journey from a bookbinder's apprentice to the Father of Electricity. His groundbreaking discoveries not only transformed the scientific landscape of his time but also paved the way for the technological advancements that define our modern era.

Faraday's work in electromagnetism
Michael Faraday, often hailed as the "Father of Electromagnetism", was an English scientist born in 1791. Despite his humble beginnings and limited education, he rose to become one of the greatest scientific discoverers of all time. Faraday's groundbreaking work laid the foundation for many technological innovations that define our modern world.
Faraday's journey into the world of science began as an apprentice to a local bookbinder and bookseller, where he developed a passion for learning and an interest in electricity. He attended lectures by eminent scientists such as Humphry Davy and John Tatum, and his engagement with scientific books ignited his curiosity about the natural world.
Faraday's experiments in electromagnetism were meticulous and innovative. In one experiment, he wrapped two coils of wire around opposite sides of an iron ring, forming a primitive toroidal transformer. When he connected one coil to a battery, he observed a brief deflection in a galvanometer attached to the second coil. He concluded that a changing current in the first coil created a changing magnetic field, which induced a current in the second coil. He described this as a "wave of electricity" propagated through the iron.
Faraday also discovered that an electric current could be induced by moving a magnet, turning an electromagnet on and off, or moving an electric wire in the Earth's magnetic field. Within a few months of his initial discovery, he built the first electric generator, albeit primitive. His work in this field was so influential that the unit of capacitance in the International System of Units (SI) is named the farad in his honour.

His influence on modern technology
Michael Faraday, often hailed as the "Father of Electricity", made several groundbreaking discoveries in electricity and magnetism that have had a profound influence on modern technology. Born in 1791, Faraday received only basic education and began his career as an apprentice bookbinder. However, his passion for learning and curiosity about the natural world propelled him into the realm of science.
One of Faraday's most significant achievements was his discovery of electromagnetic induction in 1831. Through a series of experiments, he demonstrated that a changing magnetic field could induce an electric current in a nearby wire. This revelation laid the foundation for the development of electric generators and transformers, revolutionising the field of electrical engineering. Faraday's work on electromagnetic rotary devices, such as the homopolar motor, formed the basis of electric motor technology, making electricity practical for use in technology.
Faraday also made important contributions to electrochemistry, formulating the laws of electrolysis and providing a quantitative understanding of the relationship between electric current and chemical substances in an electrolytic cell. These discoveries were pivotal in the development of electric power systems and underlie modern technologies like MRI machines.
In addition, Faraday's work on static electricity, such as his ice pail experiment, demonstrated that electricity was a force and introduced the concept of the Faraday cage, which shields objects from external electrical influences. He also discovered the Faraday effect, where an electric current applied to a coil of wire produces an electromotive force, causing the wire to move. This effect is used to generate electricity in generators.
Faraday's influence extended beyond his scientific discoveries. He popularised scientific terminology, coining terms like "anode", "cathode", "electrode", and "ion". He also applied his research to real-world problems, such as the electrification of lighthouses and long-distance telegraph signalling. Albert Einstein and Ernest Rutherford both regarded Faraday as one of the greatest scientific discoverers of all time, highlighting the profound impact of his work on the progress of science and industry.
