Electromagnetismul is a fundamental force of nature that describes the interaction between electric charges and magnetic fields. It combines electricity and magnetism into a single theory, explaining how electric currents produce magnetic fields and how changing magnetic fields can induce electric currents. This principle is essential for many technologies, including electric motors, generators, and transformers. The study of electromagnetismul is governed by Maxwell's equations, which mathematically describe how electric and magnetic fields interact. These equations reveal that light is an electromagnetic wave, linking optics with electromagnetism. Understanding this force is crucial for advancements in physics, engineering, and various modern technologies.
