New Computing Method and Technique on Solving Electric Field
This paper studied the problems on solving a static, axial symmetric and passive electric field. In the circumstances of the electric field which is limited and differentiable on a symmetric axis, it provides a new computing method and technique by using Maxwell equations. Out-of-axis electric field can be transformed into series by means of the method and technique. The series include the field on the symmetric axis and its different order derivatives. Applying the method and technique is very easy, quick and exact to perform numerical calculation. Using the method studied the electric field emitted by a point charge. Approximate calculations were performed. When choosing only the first twelve terms, on the curved surface that r and z is in a ratio of one to two, the relative errors of approximate results and their exact values of z and r components of the electric field are 0.00003％ and 0.00001％ respectively.
