FLUXGATE magnetometer - how it works

  1. May 26, 2013 #1
    Assuming that I am looking at an 'ideal' fluxgate magnetometer.


    I am feeding this transformer an ideal sine wave. The secondary winding output and the primary winding input are fed into two channels of an oscilloscope.

    A magnetic field from the outside (like earth magnetic field) is applied.

    Would I get a shift of the output signal in relationship to the input signal by X or by Y axis?

    Would this depend on the angle of the magnetic flux in relationship to the transformer?
    Would this be different for a bar transformer vs a ring transformer.

    Thank you.
