Abstract
The purpose of this work is to create a model of sources of Earth’s magnetic field. Main magnetic field in IGRF-2005 model is used as initial condition for solving inverse magnetometry problem using adaptive method of solving systems of equations. Distributions of effective magnetization, magnetic moments and volumetric currents in the Earth’s core, consistent with observed magnetic field, are obtained.
