What You'll Learn
Faraday invented the first electric motor
Michael Faraday, born in 1791, was an English chemist and physicist who made significant contributions to the fields of electrochemistry and electromagnetism. Despite having little formal education, he became one of the most influential scientists in history.
Faraday's work laid the foundation for modern electromagnetic technology. He was particularly interested in the concept of energy and force, which drove his experiments and discoveries in electricity. One of his most notable contributions was the invention of the first electric motor, which he created around 1821.
The Faraday motor was a primitive version of what we now know as an electric motor. It featured a stiff wire suspended in a container of mercury, a metal that is liquid at room temperature and an excellent conductor, with a permanent bar magnet at its centre. By sending an electric current through the wire, Faraday created a magnetic field around it, which interacted with the field of the magnet and caused the wire to rotate. This discovery was groundbreaking, as it was the first time that a magnetic field had been used to induce a current in an adjacent conductor.
Faraday's electric motor didn't have any practical applications at the time, but it was the crucial first step in the evolution of electric motor technology. Other scientists quickly built upon his work and made improvements, leading to the development of more advanced electric motors.
Faraday's invention of the first electric motor, along with his other contributions to the field of electricity, solidified his legacy as one of the greatest scientists of the 19th century. His work continues to inspire and influence scientists and researchers even today.

He discovered electromagnetic induction
Michael Faraday, born in 1791, was an English chemist and physicist who made significant contributions to the study of electrochemistry and electromagnetism. One of his most notable achievements was his discovery of electromagnetic induction, which revolutionized our understanding of electricity and magnetism.
Faraday's interest in science began at a young age when he started reading books during his job as an errand boy for a bookbinding shop. He was fascinated by the concept of energy and force, which later inspired his experiments and discoveries in electricity. In the early 1830s, Faraday embarked on a series of experiments that led him to discover electromagnetic induction.
Faraday's experiments aimed to prove that a magnet could induce electricity. He visualized that magnets, electric charges, and electric currents produce lines of force, which he believed explained the attraction and repulsion of magnets and electric charges. In 1831, after years of experimentation, Faraday successfully demonstrated electromagnetic induction using two coils of wire wound around opposite sides of a ring of soft iron. This discovery was a pivotal moment in the synthesis of electricity and magnetism into a coherent theory.
Faraday's law of electromagnetic induction, also known as Faraday's law, is a fundamental law of electromagnetism that helps predict how a magnetic field interacts with an electric circuit to produce an electromotive force (EMF). This discovery led to the formulation of Faraday's first and second laws of electromagnetic induction. The first law states that when a conductor is placed in a varying magnetic field, an electromotive force (EMF) is induced, resulting in an induced current if the conductor circuit is closed. The second law quantifies the EMF produced in the conductor, stating that it is equal to the rate of change of flux linkage.
Faraday's work in electromagnetic induction laid the foundation for modern electromagnetic technology and inspired subsequent scientists like James Clerk Maxwell, who built upon Faraday's discoveries to develop classical electromagnetic field theory. Faraday's contributions to electricity and magnetism have had a lasting impact on the field of electromagnetism and our understanding of the natural world.
