Electromagnetism deals with the interaction between electrically charged particles and electromagnetic fields. This branch of physics encompasses a wide range of phenomena, from the behavior of electric charges at rest (static electricity) to the generation and transmission of electromagnetic waves (such as light and radio waves). Key concepts include Coulomb’s law, which describes the force between electric charges, and Maxwell’s equations, which unify electric and magnetic fields and describe how they propagate through space. Electromagnetism underlies many technological innovations, from electric motors and generators to telecommunications and electronics, making it a crucial area of study in both theoretical and applied physics
