Electromagnetic Field

Also: E-field, Electric Field.

"The electromagnetic field is that part of space which contains and surrounds bodies in electric or magnetic conditions." [James Clerk Maxwell, A Dynamical Theory of the Electromagnetic Field]

An electric field is a field that surrounds electric charges. It represents charges attracting or repelling other electric charges by exerting force. Mathematically the electric field is a vector field that associates to each point in space the force, called the Coulomb force, that would be experienced per unit of charge, by an infinitesimal test charge at that point. The units of the electric field in the SI system are newtons per coulomb (N/C), or volts per meter (V/m). Electric fields are created by electric charges, and by time-varying magnetic fields. Electric fields are important in many areas of physics, and are exploited practically in electrical technology. On an atomic scale, the electric field is responsible for the attractive force between the atomic nucleus and electrons that holds atoms together, and the forces between atoms that cause chemical bonding. The electric field and the magnetic field together form the electromagnetic force, one of the four fundamental forces of nature. Wikipedia, Electric Field
