André-Marie Ampère

André-Marie Ampère was a French physicist and mathematician known for his foundational work in electromagnetism. He formulated Ampère's Law, which describes how electric currents create magnetic fields, a key concept in magnetostatics. His research laid the groundwork for understanding the relationship between electricity and magnetism, eventually leading to the development of electromagnetic theory. The unit of electric current, the ampere, is named in his honor. His contributions significantly influenced later discoveries in electromagnetism, including electromagnetic waves, shaping our understanding of the forces that govern electrical and magnetic phenomena.
