An important transition is missed, that is that magnetic amplifiers are analog amplifiers. It was William Steagall of Sperry-Rand who realized that the flux saturation could be used as a digital logic element. If you send a pulse in the same direction as the core is already magnetized, you get no output pulse. From this, and a multi-phase clock to supply drive power, digital computing elements were created. https://en.wikipedia.org/wiki/Magnetic_logic https://en.wikipedia.org/wiki/Magnetic_logic
