| Abstract: | By the circular current symmetry characteristic,on the basis of Biot-Savart law,the expression of the whole-space magnetic induction intensity distribution was deduced in the spherical coordinates system.Then,the properties of the magnetic field on the plane and the central axis of the circular current were discussed.By C language algorithms method,the main region and distribution layout of the magnetic induction intensity were plotted and then the characteristics of its distribution was showed and discussed clearly. |
