Maxwell's equations are a set of four equations that govern all electromagnetism. The equations show a unification of electric and magnetic fields and are often considered one of the greatest unifications in physics, describing one of the four fundamental interactions, the electromagnetic force. The unification of electric and magnetic forces in the 19th century through Maxwell's equations led to several scientific advances – including an entirely new branch of physics, electromagnetism – and to inventions that transformed the world, bringing to world of vast improvements in the quality of forces. life, communications and navigation. William Gilbert, an English physicist and philosopher, proposed in 1600 that electricity and magnetism were two distinct entities. However, in the early 19th century, many discoveries suggested otherwise; the experimental data implied a connection between electric and magnetic fields. Ampère, Faraday, Gauss and others had all published works capturing the phenomenon of electricity and magnetism. In 1826, André-Marie Ampère observed that two parallel wires carrying electric currents attracted or repelled each other, depending on the direction of the current. In 1821, Michael Faraday invented the concept of electric and magnetic fields. He also discovered electromagnetic induction: a potential difference would be generated in a conductor when exposed to a varying magnetic field. In 1835, Carl Gauss associated electric charge with the electric field. Despite these advances, known information about electricity and magnetism existed in a fragmentary manner. A real theory to unify electric and magnetic fields was lacking until users, such as smartphones or military vehicles, on Earth could use data from satellites to calculate their position. Through the use of special relativity and wireless transmission, both dependent on Maxwell's equations, GPS allows modern humans to orient themselves to a location when traveling, track the location of a lost phone (or any object equipped with a receiver) and many other things. .The four elegant equations that make up Maxwell's equations have given rise to numerous scientific discoveries, theories and inventions with applications in everyday life. From quality of life to communications to navigation, Maxwell's equations have reshaped the way humans live and interact through the unification of electric and magnetic fields. For this reason, the conception of Maxwell's equations constitutes the most influential advance in physics in history..
