An electric field is a vector field that shows the direction that a positively charged particle will move when placed in the field. Electric fields are produced around objects that have electrical charge, or by a magnetic field that changes with time. Electric field lines are used to represent the influence of electric field.  The idea of an electric field was first made by Michael Faraday.
