1. A method of estimating a magnetic property of a downhole component, comprising:
measuring a magnetic field strength of the downhole component at a plurality of axial locations along the downhole component to generate a plurality of magnetic field strength measurements, each magnetic field strength measurement taken in a near field region of the downhole component;
analyzing the plurality of magnetic field strength measurements to estimate a magnetic signature of the downhole component;
estimating an expected maximum pole strength of the downhole component based on the magnetic signature; and
configuring the downhole component in a borehole string based on the expected maximum pole strength.
