Abstract
For high precision measurement of geomagnetic field, the induced magnetic field calculations for ferromagnetic objects have certain theoretical guidance meaning when degaussing. The influence of induced magnetic fields in ferromagnetic objects in a weak magnetic field was studied for this paper. Based on far magnetic field of magnetic dipoles, three magnetic dipoles are used to simulate the ferromagnetic objects; the formula of magnetic induction in space any point can be obtained. The influence of ferromagnetic objects on space magnetic field was approached theoretically as well as experimentally. Finally, calculation for a nail example showed that the established model is effective in practical engineering.
