<P> 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 . </P>
