It was at a very early time that our ancestors gained knowledge by intuition and experience about some electromagnetic phenomena of electrification by friction and magnet. Until the end of European Renaissance, experiments had made to study the static and static magnetic phenomena. Royal Dr. Gilbert (1540-1603) first proposed the initial electromagnetic theory. In 1752, American scientist Franklin (1706-1790) had done a famous experiment of catching the thunder and lightning with the kite, which proved that the lightning was the same electric discharge phenomenon as the electrification by friction; thereby, it was realized that there exists two kinds of electricity, positive and negative, as the like charges repulse, the unlike charges attract...
