On the Inversion of the Magnetic Field lth - Derivative Equations for a Point 2 to the lth power -Pole Magnetic Field
Abstract
A general procedure is outlined for inverting the magnetic field derivative equations for a point 2 (to the l power)-pole magnetic field. The procedure is believed to be valid for arbitrary l although an explicit proof has been obtained only for l = 0, 1, and 2. The details for l = 2 are included. Utilization of the procedure permits a determination of the bearing of the source and the scaled multipole moments of the source; i.e., the moments divided by a power of the source-to-detector distance, from a knowledge of the field derivatives at a single space point only. The procedure makes use of a spherical basis representation in which only the independent multipole moments and field derivatives occur.
