Who was Andre Ampere and what did she do?

André-Marie Ampère was a French physicist and mathematician born in 1775, known for his foundational contributions to the field of electromagnetism. He formulated Ampère's Law, which describes the relationship between electric current and the magnetic field it produces. Ampère's work laid the groundwork for the science of electrodynamics, and he is considered one of the key figures in the development of electrical engineering. The unit of electric current, the ampere, is named in his honor.
