Glossary term: Electric Field

Description: Electrically charged particles attract or repel each other via the electric force – like charges repel, opposite charges attract. In physics, it has proven practical to divide the action of one charge on others into two steps: Every particle that carries an electric charge is taken to produce a so-called electric field in the surrounding space. The force acting on a second particle is given directly by the direction and strength ("field vector") of the electric field at the location of that second particle: multiply the field with the value of the second particle's electric charge, and you obtain the force acting on that second particle.
