Abstract

Summary

Method to calculate power and angular components of induction vector of the Earth’s magnetic field is proposed. This method is grounded on the development of 3D model of the Earth’s crust and following calculation by it of northern (Δb), eastern (ΔB) and vertical (ΔB) components of anomalous magnetic field that together with corresponding components (B, B, B) of normal field enable to define full values of B -, B -, B - components of the Earth’s magnetic field. Using them the value of horizontal component (BH) as well as the angles of declination D and inclination J of geomagnetic field are calculated. The values of power and angular components of B magnetic field on the territory of Bulgaria for the Epochs 1960 and 2010 years as well as its 60 years dynamics are calculated. The contribution into magnetic declination D and inclination I of its normal (D, I) and anomalous (ΔD, ΔI) components is estimated.
