i think that electrical engineers are the beginers of this world
The Greeks had some idea of electricity.
In the 18th century Franklin and other Europeans knew a great deal about it. Early in the century, Alessandro Volta invented the first source of continuous electric current - the battery. Later, Hans Christian Oersted discovered that an electric current produced magnetism.
But it was Michael Faraday who described the nature of the phenomena. In his electromagnetic induction theory he stated that an electric current flows in a conductor if that conductor is in a moving magnetic field and is part of a circuit.
