Modeling of Earth Magnetic Field Disturbances Induced by Ferromagnetic Objects
Modeling of Earth Magnetic Field Disturbances Induced by Ferromagnetic Objects
摘要
This paper presents the methodology and results of modelling of Earth magnetic field disturbances induced by ferromagnetic objects. The modeling was carried out using the finite elements calculations, and the results were compared with the measurements. The special test stand, consisting of magnetovision scanner and Helmholtz coils, has been used. The measurement system is able to measure the distribution of planar magnetic induction vectors, and to differentiate the sources of measured disturbances.
