Electrostatics,until the eighteenth century when du Fay showed that there were two sorts of charge. One sort followed the rubbing of an amber rod with wool, the other a glass rod with silk. It was Benjamin Franklin who arbitrarily named the latter a positive charge and the original amber one a negative charge. He

Electric potential and fields, important properties of a vector field are its flux and its circulation. For the electrostatic field these are expressed by integral equations (2.9) and (2.10) as follows:. In this chapter theorems from vector analysis are used to derive the differential forms of these equations and hence to descri

Electromagnetism and relativity,e can investigate the electric and magnetic fields of rapidly moving charges. Then by introducing a vector potential . subject to the Lorentz gauge condition we find a remarkable similarity between the equations of electrostatics, expressed in terms of the scalars . (potential) and ., and the equati
