In physics, an electric field or E-field is an effect produced by an electric charge that exerts a force on charged objects in its vicinity. The units of the electric field are newtons per coulomb or volts per meter (both are equivalent). Electric fields are composed of photons and contain electrical energy with energy density proportional to the square of the field intensity. ...

1. A vector field, usually denoted by E, defined as follows: at a given time and at each point in space the force experienced by a positive charge (sometimes called a test charge) at that point divided by the magnitude of the charge, taken to be sufficiently small that it does not affect the positions and velocities of all other charges. The set of all vectors thus obtained is the electric field, although this term is often used for its value at any given point. ...

The region around any electrically charged material contains an electric field that affects other charged objects. The field around a negatively charged material pulls positively-charged objects in toward the material, while negatively-charged objects are pushed away. Around a positively charged material, on the contrary, negative objects are attracted and positive objects are repelled. The strength of the field gets rapidly weaker as one moves further away from the charged material.
