Abstract

A method of estimating a magnetic property of a downhole component includes 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, and analyzing the magnetic field measurements to estimate a magnetic signature of the downhole component. The method also includes 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.
