The magnetic flux distribution created by the currents at instant 2 is shown in Figure 5c . Eventually at instant 3 , the currents are

The magnetic flux distribution created by the phase currents given by equation 4 is shown in Figure 5d . From Figure 5b to 5c it can be seen that the 2 poles produced by the resultant flux are seen to have turned 60°. At other instants of time, i.e. as time elapses, the two poles rotate further. In this manner a rotating magnetic field is produced. The space angle traversed by a rotating flux is equal to the time angle traversed by currents.

After having discussed the production of rotating magnetic field, an important issue that still remains unresolved is: How to create the second magnetic field that will follow the rotating magnetic field created by the stator? This question is answered in following section.
