6. 2 the phase will be the average of -π/4 and +π/4, i.e., zero phase. In this model the sum of all such fringing currents still has a real part strictly proportional to x and imaginary part to y. Thus, the overall effect of fringing is only to slightly change the absolute magnitude of the injected current.
