👉 Electromagnetic, or EM, refers to a phenomenon in which electric currents and magnetic fields interact with each other. It is often used in electrical engineering and physics, particularly in the study of wireless communication systems, radio waves, and other electromagnetic phenomena. In simple terms, EM describes how electricity flows through materials and how the movement of charged particles like electrons or protons interacts with the magnetic field around them. This interaction can result in a phenomenon called "emf," which is energy stored by the
