How can we calculate the magnetic field of moving charge by the Maxwell equation ##\nabla \times H=J+\frac {\partial D} {\partial t}##? I mean which term, ##J## or ##\frac {\partial D} {\partial t}##, should be taken into account in calculations? The first, second, or both? Can we deal with the moving charge as a current wire with the magnetic field ##B=\frac{\mu_0 I}{2\pi r}##? If yes, what about the term ##\frac {\partial D} {\partial t}##?
