Abstract :
The determination of presence and location of the magnetic interference source in DC or VLF band is a very complicated procedure which needs in the common case the displacement or rotation of the investigated objects. A new method of the components of equivalent magnetic dipole momentum and its position determination is proposed which does not need any displacements of a stationary object. It is based on synchronous measurements of different combinations of magnetic field horizontal components using two rotating platforms with fixed distance between the axes. The method allows one to exclude the influence of the majority of systematic errors including those produced by the presence of ambient magnetized bodies and the Earth´s magnetic field
