Electromagnetism is a branch of physics that deals with the study of electromagnetic fields, which are created by the interaction of electric currents and magnetic materials. This field of study encompasses a wide range of phenomena, including the behavior of charged particles in electric and magnetic fields, the generation of electromagnetic radiation (such as light and radio waves), and the interactions between electric and magnetic fields. Electromagnetism is fundamental to many areas of science and technology, including electricity, magnetism, electronics, communication systems, and modern physics.
