1. A method for generating a property estimation grid for use with a magnetometer for measuring preselected properties of a material comprising the steps of:

  • a) defining physical and geometric properties for a material including preselected properties of the material;

    b) defining operating point parameters and a winding geometry and winding configuration for the magnetometer;

    c) inputting the material properties, the operating point parameters and the magnetometer winding geometry and configuration into a model to compute an input/output terminal relation value;

    d) recording the terminal relation value as a property estimation grid point;

    e) adjusting the preselected properties of the material and repeating steps c) and d).
