Maxwell's electromagnetic theory is the basis of electromagnetism and a unified theory to describe electromagnetic field. Maxwell's electromagnetic theory not only solved a series of problems in electromagnetism, but also laid the foundation for the discovery of electromagnetic waves and the realization of radio communication.

Basic concepts of Maxwell's electromagnetic theory

The basic concepts of Maxwell's electromagnetic theory include electric field, magnetic field, charge, current and electromagnetic wave. Among them, electric field and magnetic field are two basic elements of electromagnetic field, and they interact to form electromagnetic waves. Charge and current are the sources of electromagnetic fields, which produce electric and magnetic fields.

Maxwell equations

The core of Maxwell's electromagnetic theory is Maxwell's equations, which are composed of four equations, namely Gauss's law, Ampere's law, Faraday's law of electromagnetic induction and Maxwell-Ampere's loop theorem. These four equations describe the generation, propagation and function of electromagnetic field.

Application of Maxwell's electromagnetic theory

Maxwell's electromagnetic theory is widely used, involving electromagnetic waves, radio communication, radar, television, computers and other fields. Electromagnetic wave is one of the important predictions of Maxwell's electromagnetic theory. Its discovery and application have changed the way of human communication and enabled people to realize long-distance wireless communication.
