【Abstract】 After reviewing the double 4 dimensional potentials of the electromagnetic field theory in the presence of magnetic charge (or effective magnetic charge), we give out the electromagnetic (EM) duality symmetric Maxwell equations and the relationship between the field strength and the double potentials. Then by using the Green function method we find the Lorentz invariant retarded solutions of the field equations, and finally obtain the explicit expressions of the generalized Lienard-Wiechert potentials.更多还原
