Schematic representation of field lines of electric field around a negative electric charge.
An electric charge moving at a constant velocity v generates electric and magnetic field attached with the charge (green area). A sudden deceleration of the charge (grey small circle), from moving to stationary, creates an electromagnetic pulse (red ring) which radiates away into space at the speed of light. A static charge (dark blue circle at the centre) generates electrostatic field (blue area).
