Electromagnetism is a fundamental force of nature that describes the interaction between electrically charged particles. It encompasses both electricity and magnetism, revealing that these two phenomena are deeply interconnected and are two aspects of the same underlying force. Electric fields are produced by stationary electric charges, while magnetic fields are produced by moving electric charges (electric currents) and by magnetic materials.

The interaction between electric and magnetic fields is described by Maxwell's equations, a set of four fundamental equations that form the basis of classical electrodynamics. These equations explain a vast range of electromagnetic phenomena, including the behavior of light, radio waves, and other forms of electromagnetic radiation. Electromagnetic radiation consists of oscillating electric and magnetic fields that propagate through space at the speed of light.

Electromagnetism has profound implications for technology and daily life. It is the principle behind electric motors, generators, transformers, and virtually all electronic devices. Understanding electromagnetism is crucial for fields such as physics, electrical engineering, and materials science. The force of electromagnetism is responsible for holding atoms and molecules together, making it fundamental to the structure of matter itself.
