P. J. Wallbrink,D. E. Walling,Q. Heroper understanding of the nature of matter. We shall therefore discuss dielectric behaviour in the chapter on electrostatics, conduction in metal wires in that on magnetostatics, and magnetism in matter (whether para-, dia- or ferromagnetism) in the chapter on magnetism. In this first chapter the nature of matter is summarised.

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
