| Abstract: | Some research papers have discussed a method of counting the electric field and magnetic field that distribute in the space of long cylinder which is electrified evenly.But the method is relatively complet.In this paper,the author shows the easiest one that can draw out the resrlt quickly,and further more,it discusses the simple and direct method in counting about electric field over the ball suraface electric field evenly and the magnetic field caused by the even vertical electric current over the surface of cylinder,and therefore,draws an important conclusion. |
