Theory of Electromagnetism

The theory of electromagnetism describes how electricity and magnetism are related aspects of a single fundamental force. When electric charges move, they generate magnetic fields, and changing magnetic fields can induce electric currents. This interconnected behavior explains phenomena like electromagnetism waves, including light, radio, and X-rays. Formulated in the 19th century by scientists like Maxwell, the theory unifies electric and magnetic forces, forming the basis for modern technologies such as electric motors, generators, and communication systems. It reveals that electric and magnetic effects are different manifestations of the same underlying force, essential for understanding how the universe interacts at a fundamental level.
