NARRATIVE
       The induction motor utilizes alternating current and the fact that current leads the voltage by 90 degrees in a capacitive circuit to produce a two phase rotating magnetic field. This field induces any one of a number of different armatures to rotate. B and A are always 90 degrees out of phase because one of these circuits contains a capacitance which causes a voltage lag.
