André-Marie Ampère was born on January 20, 1775, in Lyon, France, and died on June 10, 1836, in Marseille, France. Ampère, despite enduring a tumultuous childhood marked by the execution of his father during the French Revolution, maintained a strong passion for learning. His mother took charge of his education, and by the age of 12, he had already mastered all the standard school subjects.
Although he was largely self-taught, his immense dedication to knowledge and scientific inquiry led him to become a professor at the University of Lyon and later the Collège de France in Paris. His love for science, particularly physics, was sparked by reading an article about electricity and magnetism, which profoundly influenced him and shaped his future work.
Ampère is best known for his work on electromagnetism. Inspired by the discovery of electromagnetic phenomena by Hans Christian Ørsted, Ampère conducted several experiments and made significant advancements in understanding the relationship between electricity and magnetism.
His experiments led to the discovery that parallel wires carrying electric currents attract or repel each other, depending on whether the currents flow in the same or opposite directions. This discovery laid the groundwork for the development of electromagnetism theory.
Like many scientists of his time, Ampère faced considerable challenges, such as limited resources and the absence of sophisticated experimental equipment. Nevertheless, his persistence and creativity in experimental design allowed him to make important scientific discoveries.
Ampère's primary achievement is his foundational work in electromagnetism. His experiments and theoretical insights led to the development of Ampère's circuital law, which describes the magnetic field generated by an electric current. He is also recognized as one of the founders of the science of classical electromagnetism. The unit of electric current, the Ampere (A), is named after him.
Ampère's circuital law, a fundamental principle in electromagnetism, can be stated mathematically as:
