In this paper, we propose a B-spline finite element method to calculate the complex magnetic potential, which reduces the amount of computer memory occupied by the complex magnetic potential distribution in the field of interest and solves complex computational problems by using the microcomputer. The direct current method and the energy method are used to calculate the impedance of the energized coil and compared with the analytical results and the general finite element calculation results. The results show that the proposed method is economical and effective.
