Ampere's Experiment

Ampère's experiment demonstrated how electric currents create magnetic fields. He observed that when two wires carry current, they exert forces on each other: parallel currents attract, while opposite currents repel. By carefully arranging and measuring these forces, Ampère proved that electric currents generate magnetic effects, laying the foundation for understanding electromagnetism. His work showed a direct relationship between electricity and magnetism, which is fundamental to many technologies today, such as electric motors and transformers.
