By magnetostatics we, of course, don’t mean that the charges are static but rather the magnetic fields, electric fields and currents are constant in time. Thus,magnetostatic fields originate from currents (for instance,direct currents in current-carrying wires). These 4 equations are Maxwell's Equations for static electromagnetics.
