摘　　要：文章在假想的"磁荷世界"中修改了麦克斯韦方程组和洛伦兹力公式.由磁的库仑定律出发,并根据磁荷与电荷产生的电磁场的等效性,得到真空中静磁场的高斯定理和环路定理.仿照"电荷世界"中的电流定义了磁流强度,又根据磁场的相对论变换,由毕奥一萨伐尔定律和法拉第电磁感应定律得到稳恒电场D的高斯定理和环路定理.In this paper, we modified the Maxwell equations and the Lorentz force formula in the supposed ＂magnetic charge world＂. Based on the Coulomb＇s law for magnetism and the equivalence between the electromagnetic fields produced by electric charge and magnetic charge, we obtained the Gaussian loop theorem for the static magnetic field in vacuum. Mod- eling on the current in the ＂electric charge world＂, we defined the intensity of magnetic fluid. According to the relativity transformation in the magnetic field, we got the Gauss theorem and the loop theorem of the characteristic electric field D from the Biot--Savart Law and the Fara- day law of electromagnetic induction.
