Electromagnetism is a fundamental force of nature that describes the interactions between electrically charged particles. It encompasses electricity and magnetism, which are two aspects of the same underlying phenomenon. Electric phenomena arise from stationary electric charges, while magnetic phenomena are associated with moving electric charges, also known as electric currents. These two are intrinsically linked; a changing electric field generates a magnetic field, and a changing magnetic field induces an electric field.

The basic principles of electromagnetism are mathematically described by Maxwell's equations. These equations unify electricity, magnetism, and light, showing that light is an electromagnetic wave. Electromagnetism governs a vast range of phenomena, from the attraction and repulsion of magnets to the operation of electric motors, generators, and radio waves. It is crucial for understanding the behavior of atoms and molecules, chemical bonding, and the properties of materials.

The study of electromagnetism has led to numerous technological advancements. Electricity powers our homes and industries, while magnetism is used in data storage, medical imaging (MRI), and transportation (maglev trains). Radio waves, a form of electromagnetic radiation, enable communication technologies like broadcasting, mobile phones, and Wi-Fi. The electromagnetic spectrum also includes visible light, X-rays, and gamma rays, each with its own applications and implications in science and technology.
