This webpage explores the life, discoveries, and enduring legacy of Michael Faraday, highlighting his journey from modest beginnings to becoming one of history’s most celebrated scientific minds.
🌟 Early Life and Background
🍼 Birth and Family
Michael Faraday was born on 22 September 1791 in Newington Butts, London, England, a modest neighborhood south of the River Thames. He was the third of four children in a working-class family. His father, James Faraday, was a blacksmith who struggled to provide for the family, while his mother, Margaret Hastwell Faraday, managed the household. The Faradays were devout Christians and emphasized moral values and hard work, which deeply influenced Michael’s character and ethical approach to science later in life.
🏚 Childhood Circumstances
Faraday grew up in a humble home without luxuries. His family’s financial struggles meant he had very limited formal education. He attended a local school for a short period, learning only the basics of reading, writing, and arithmetic. Despite these limitations, Michael showed remarkable self-discipline and curiosity, often reading by candlelight after long days of helping his father with work. His early experiences taught him resilience, patience, and the value of hard work—traits that would define his scientific career.
📚 Early Influences
At the age of 14, Michael Faraday became an apprentice to a local bookbinder, George Riebau. This apprenticeship was crucial for his intellectual development. Handling books exposed him to a wide variety of scientific and literary texts, sparking a lifelong love for reading and learning. He often copied passages from books to understand them better, a practice that enhanced his observational skills and meticulous note-taking—skills that would later define his laboratory work.
🔬 Early Curiosity in Science
Faraday’s interest in science was kindled by reading books such as The Encyclopaedia Britannica and John Tatum’s Journal of Natural Philosophy. He was fascinated by electricity, magnetism, and chemical experiments, even attempting small experiments at home with rudimentary equipment. This early self-directed study laid the groundwork for his experimental genius. Faraday’s curiosity was not just academic; he was driven by a desire to understand nature deeply and systematically, a mindset that would guide him throughout his life.
🌱 Apprenticeship and First Exposure to Science
🛠 Apprenticeship with George Riebau (1805–1812)
At the age of 14, Michael Faraday began an apprenticeship with George Riebau, a local bookbinder in London. During this seven-year apprenticeship, Faraday learned the craft of binding, folding, and repairing books—skills that demanded precision, patience, and attention to detail. While the work itself was modest, it exposed him to a wide variety of books, including scientific texts that would ignite his curiosity. This period was crucial: it combined practical work with intellectual growth, shaping his meticulous approach to experimentation later in life.
📖 Self-Education and Scientific Curiosity
Faraday used his spare time during the apprenticeship to teach himself science. He copied passages from books word-for-word to understand complex concepts, a method that helped him internalize knowledge deeply. He studied subjects such as chemistry, electricity, and magnetism, often conducting small experiments at home using rudimentary equipment like magnets, wires, and chemical compounds. These early experiments allowed Faraday to develop a hands-on understanding of natural phenomena, long before formal laboratory training.
🎓 Attendance at Humphry Davy’s Lectures (1812)
In 1812, Faraday attended a series of lectures at the Royal Institution by Sir Humphry Davy, one of the most famous chemists of the era. Faraday was captivated by Davy’s demonstrations of chemical reactions and electrical experiments. These lectures were pivotal: they inspired him to pursue a career in experimental science. Faraday took detailed notes during every lecture, filling notebooks with observations, questions, and sketches of experimental setups. His diligence and insight did not go unnoticed.
✉ Sending the 300-Page Notebook to Davy
Determined to make a professional connection, Faraday bound a 300-page notebook of his lecture notes and sent it to Davy in 1812. The notebook showcased his accuracy, observational skills, and grasp of complex scientific ideas, despite his limited formal education. Impressed by Faraday’s dedication and talent, Davy offered him a position as assistant at the Royal Institution in 1813, marking the beginning of Faraday’s professional scientific career. This moment was a turning point: a self-taught apprentice from a poor family became the protégé of one of Britain’s greatest scientists.

A magnetized needle could rotate around a wire carrying an electric current.
Magnetic forces could produce continuous motion when arranged in a circular path.
This experiment proved the direct relationship between electricity and magnetism, confirming theoretical predictions and opening the door to practical electrical machines.
Although primitive, this experiment laid the conceptual foundation for electric motors, which would become essential to industry and technology decades later.
⚡ Discovery of Electromagnetic Induction (1831)
Faraday’s most celebrated achievement came in 1831, when he discovered electromagnetic induction:
He observed that a changing magnetic field around a coil of wire induced an electric current in the wire.
This principle, now known as Faraday’s Law of Electromagnetic Induction, mathematically expresses that the induced voltage in a circuit is proportional to the rate of change of magnetic flux.
Faraday’s meticulous experiments demonstrated the reversible and predictable relationship between magnetism and electricity.
This discovery was groundbreaking because it showed that electricity could be generated mechanically, not just chemically, transforming the future of energy production.
🔋 How Changing Magnetic Fields Induce Currents
Faraday explained the mechanism of electromagnetic induction in simple terms:
A magnetic field moving relative to a conductor creates an electric current in the conductor.
The faster the change in the magnetic field, the stronger the induced current.
This insight bridged theoretical understanding and practical application, proving that electricity and magnetism are deeply interconnected.
🏭 Foundation for Modern Electricity
Faraday’s discoveries paved the way for modern electrical engineering and technology:
Inspired electric generators, which convert mechanical energy into electrical energy.
Led to transformers, which regulate voltage in electrical systems.

Through these achievements, Faraday not only transformed physics but also laid the technological groundwork for the electrical age, affecting every aspect of modern life from power generation to communication systems.
⚡ Contributions to Electrochemistry
🔬 Research on Electrolysis and Ionic Theory
Michael Faraday was a pioneer in electrochemistry, the study of the relationship between electricity and chemical reactions.
He conducted systematic experiments on electrolysis, passing electric currents through liquids to decompose chemical compounds.
Faraday observed that specific amounts of chemical substances were deposited or liberated at the electrodes depending on the current used.
His work provided early support for ionic theory, confirming that electricity in chemical reactions involves the movement of charged particles (ions).
These experiments were meticulously documented, demonstrating Faraday’s commitment to precision and reproducibility.
⚖️ Faraday’s Laws of Electrolysis
Faraday formulated two fundamental laws, which became cornerstones of electrochemistry:
First Law: The mass of a substance deposited or liberated at an electrode during electrolysis is directly proportional to the amount of electric charge passed through the substance.
Second Law: The masses of different substances liberated by the same quantity of electricity are proportional to their equivalent chemical weights.
These laws allowed chemists to quantitatively predict chemical changes from electrical current, bridging chemistry and physics in a precise, measurable way.
📝 Coining of Key Terminology
Faraday also contributed to the language of electrochemistry, creating terms that are still universally used today:
Electrode: The conductor through which electricity enters or leaves a solution.
Anode and Cathode: Designations for positive and negative electrodes.
Ion: Charged particle that moves during electrolysis.
These terms provided a common framework for scientists to describe and understand electrochemical processes clearly.
