Warning! There are problems with both Figures 2-32 and 2-33. OK in principle but in practice those circuits would result in AC current flowing in the DC control winding. More common practice would be to use a 3-leg magnetic circuit. The power winding would be the center one. Outer two windings would carry the control current and be connected in series such that the magnetic field the produce would be in the same direction in the center leg but that the induced voltages from the power winding would cancel out..
