The Flux Valve provides an electronic indication of the location of the aircraft relative to the earth's magnetic field. This is achieved by exciting a single coil mounted on a "hooks joint", with 400 Hz ac. As the aircraft passes through the earth's magnetic field >a flux is induced< in the three arms and the windings produce and emf which is proportional to the direction of the earth's magnetic field. This "synchro" type signal is sent to the amplifier.
