Electromagnetism is one of the four essential forces in Physics (the others are gravity and the weak & strong nuclear forces). Hans Christian Oerstad is credited with its discovery in 1820, and Michael Faraday is generally credited with its early development. It plays an important role in modern society through electric power generation, communications, motors, generators, hybrid cars, military hardware, medical industry, and countless other areas.
