Claim One:
1. A method of locating a magnetic object disposed in a environment in which a system of coordinates is defined comprising an abscissa axis, an ordinate axis and a height axis, said method comprising: a phase of measuring at least one magnetic parameter at a plurality of measuring points in the environment in order to obtain a plurality of recorded values of this parameter at the said measuring points that form a grid of recorded values; a phase of exploiting the recorded values, comprising the following steps, at least one of which being performed by a computer: constructing at least a first vector and at least a second vector; obtaining at least one pseudo angle formed by said at least one first vector and said at least one second vector; obtaining at least one vertical curvature of a function of at least one pseudo angle with respect to height along the height axis; and applying said at least one vertical curvature to the recorded values in order to obtain an estimated value of a parameter proportional to a susceptibility at a plurality of estimated points in the environment making it possible to obtain a location of said object.
