The concept of the electric field was first introduced by 19th century physicist Michael Faraday. It was Faraday's perception that the pattern of lines characterizing the electric field represents an invisible reality.
The field can be viewed as the combination of an electric field and a magnetic field. The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field.The way in which charges and currents interact with the electromagnetic field is described by Maxwell's equations and the Lorentz force law.he electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field.
