2 The electric field is defined as the force on a small test charge, divided by the magnitude of the charge: 21-6 The Electric Field The Electric Field points away from a positive charge and toward a negative charge. 21-6 The Electric Field An electric field surrounds every charge. We live in a sea of electric and magnetic field lines, but we are usually not able sense them. The Electric Field points away from a positive charge and toward a negative charge. For a point charge: 21-6 The Electric Field Force on a point charge in an electric field: 21-6 The Electric Field Sign of charge determines if the force is in the direction of the field.
