Electromagnetism is a fundamental force of nature that describes the interaction between electrically charged particles. It encompasses both electric fields, which arise from stationary charges, and magnetic fields, which are produced by moving charges. This force is responsible for a wide range of phenomena, from the behavior of atoms to the functioning of everyday electronic devices like smartphones and computers. The theory of electromagnetism is encapsulated in Maxwell's Equations, which unify electricity and magnetism into a single framework. This unification has profound implications, leading to the development of technologies such as radio, television, and wireless communication, which rely on electromagnetic waves to transmit information across distances.
