Abstract—The model of variations in the Earth’s magnetic field with random Gaussian coefficients is considered. It is shown that at small amplitudes of random nondipole field component σ, the scatter of the direction of the virtual geomagnetic pole grows with increasing latitude. At large σ, the scatter does not change much and its maximum is located at middle latitudes.

Notes
It is sufficient to try to write Maxwell’s equations in terms of D and I in order to understand how inconvenient these quantities are for physics—e.g., due to the violation of the superposition principle, or the appearance of parasitic frequencies in the time spectra for D and I (Petrova and Reshetnyak, 1999), etc.
