Electromagnetism is the fundamental force that governs the behaviour of electric and magnetic fields. It encompasses the generation, interaction, and propagation of these fields as electromagnetic waves, and includes the principles and phenomena related to these interactions.
In its broadest sense, electromagnetism refers to the entire realm of phenomena arising from the fundamental electromagnetic force. This includes:
- The electromagnetic force itself: The interaction between electrically charged particles, causing attraction or repulsion.
- Electromagnetic fields: Invisible fields associated with charged particles and currents, exerting forces on other charged particles.
- Electromagnetic radiation: Energy travelling in the form of waves or particles (photons), such as light, radio waves, and X-rays.
