The xterm in the upper right corner is used to edit the inputfile, the xterm in the lower right is used to feed gd1 with the inputfile, and the long xterm on the right side runs another instance of gd1.

Electric Field Lines
... 3.At every point in space, the eld vector at that point is tangent to the eld line at that same point. 4.The eld line density at any point in space is proportional to (and therefore is representative of ) the magnitude of the eld at that point in space. 5.Field lines can never cross. Since a el ...

History of electromagnetic theory
For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
