Sources of electric field. Causes and description. Electric fields are caused by electric charges or varying magnetic fields. The former effect is described by Gauss's law, the latter by Faraday's law of induction, which together are enough to define the behavior of the electric field as a function of charge repartition and magnetic field.
electric field-a field of force surrounding a charged particle. electrostatic field-electric field associated with static electric charges. field of force, force field, field-the space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with it.
