Maxwell's Equations: James Clerk Maxwell formulated a set of four differential equations, known as Maxwell's equations, which describe the behaviour of electric and magnetic fields. These equations relate to electric field (E), magnetic field (B), electric charge, and electric current. Maxwell's equations provide a mathematical framework for understanding the generation, propagation, and interaction of electromagnetic waves. Coulomb's Law and Gauss's Law: Coulomb's Law describes the force between electric charges, while Gauss's Law for electricity relates the electric field to the distribution of electric charges. These laws establish the foundation for understanding static electric fields and the behaviour of electric charges. Ampere's Law and Faraday's Law: Ampere's law relates the magnetic field to electric currents and changing electric fields, while Faraday's law of electromagnetic induction explains how a changing magnetic field induces an electric field. These laws form the basis for understanding magnetic fields, electromagnetic induction, and the generation of electric currents.
