title: Inverse problem solution in magnetisation studies.
abstract: Magnetic measurements of the remanent field produced by dust particles in the lungs of industrial workers have increased our knowledge of the total amount of dust, the clearance rate of this dust, and the progression of phagocytosis of the particles in the lungs. To estimate the dust load from the magnetic field measurements one has to calculate the dipole moment of the magnetised lung. We conclude from a theoretical model study that an analysis of the data that uses the dipole and quadrupole coefficients to find the origin of a multipole expansion of the field gives the most accurate results.
