Electromagnetism is a fundamental force of nature that describes the interactions between charged particles and the electromagnetic field. It encompasses both electricity and magnetism, which are interrelated phenomena. This force is responsible for a range of physical phenomena, including the behavior of electric currents, the generation of magnetic fields, and the emission of light. The theory of electromagnetism is articulated in Maxwell's equations, linking electric and magnetic fields into a cohesive framework. Electromagnetism is crucial for various technologies, including electrical power generation, telecommunications, and medical imaging techniques like MRI.
