Electromagnetic refers to phenomena involving electric and magnetic fields. These fields are intrinsically linked and can influence each other. An electric field is a region around an electric charge where another charge would experience a force. A magnetic field is a region around a magnetic material or a moving electric charge where a magnetic material would experience a force.

Electromagnetic forces are one of the four fundamental forces of nature. They are responsible for a vast array of everyday occurrences, from holding atoms together to the operation of electronic devices. Light itself is a form of electromagnetic radiation, a wave that travels through space at a constant speed, the speed of light. This radiation encompasses a spectrum of wavelengths, including radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays, each with different properties and applications.

The interaction of electric and magnetic fields is described by Maxwell's equations, a set of fundamental laws that govern classical electromagnetism. These equations explain how changing electric fields create magnetic fields, and how changing magnetic fields create electric fields, leading to the propagation of electromagnetic waves. The study of electromagnetism has been crucial for technological advancements, enabling the development of electricity generation, telecommunications, and medical imaging, among many other fields.
