Electromagnetism is a fundamental branch of physics that studies the interactions between electric charges and magnetic fields. It encompasses a wide range of phenomena, from the behavior of charged particles to the propagation of electromagnetic waves, such as light. The theory of electromagnetism is described by Maxwell's Equations, which unify electricity and magnetism into a single framework. This field has numerous applications in everyday life, including the functioning of electric motors, generators, and communication technologies. Understanding electromagnetism is essential for advancements in various scientific and engineering disciplines, making it a cornerstone of modern technology.
