What did Mr. Ampere discover?

Answer 1

Mr. Ampere discovered the principle of electromagnetism and formulated Ampere's Law, which describes the relationship between electric currents and magnetic fields. He also discovered that two parallel currents attract each other when they flow in the same direction, and repel each other when they flow in opposite directions. These discoveries were critical in the development of the field of electromagnetism and have had far-reaching implications in various technological applications.
