| Abstract: | The fields of some of the charged objects and current carrying objects with certain symmetries are cal- culated using the symmetry concept and symmetry analysis method, and especially, the key points in dealing with such problems are investigated in detail. In dealing with these problems, symmetry analysis method can make the physical pictures more clear, the calculations more simple, and the understanding much easier. |
