It is well known that there are three kinds of electrostatic forces: gradient force, image force, and the Coulomb force. The gradient force acts on a non-charged body that is placed in a convergence electric field. Image force acts on a charged body placed nearby a conductive plate. The Coulomb force acts on a charged body placed in an electric field. As for the shape of these bodies, only symmetric forms have been treated in the past. The representative example for all three force types is globala sphere. Forty years ago, potential of a spherical body could be calculated. In contrast, today we can calculate the potential of any shape by computer simulation. In this book, simulation of the electrostatic force that acts on asymmetrically shaped conductors is carried out.
