as we know whenever there is change in flux wmf will induce
so by this principle we can say that rotor is running at
synchronus speed and by exciting it we create north and
south pole permanantely on it now for two pole alternator
after each 180 degree rotation pole change their position
and thus change in flux occur which induce emf in stator
