Why is Maxwell’s equation known as the foundation of classical electromagnetism?

       Maxwell’s equations refer to a set of four equations that describe the creation and propagation of electric and magnetic fields. They are named after the Scottish physicist James: Clerk Maxwell, who made significant contributions to unify the theories of electricity, magnetism, and light. The early form of these equations was published between 1861 and 1862, and it proposed that light is an electromagnetic phenomenon.

       The equations formed from these laws could give an explanation to many phenomena around. For instance, how hair stands on end when one removed a nylon sweater, how a compass needle points north all the time, how a power station turbine generates electricity etc. Together, they could also describe the transmission of radio waves, and the propagation of light.

       Hence, Maxwell’s equation, along with the Lorentz force law, is said to form the foundation of classical electromagnetism. Lorentz force law describes the force acting on a moving point charge ‘q’ in the presence of electromagnetic fields.
