Abstract: The study calculates the geomagnetic field induction vector power and its angular components for the territory of Ukraine for the 2024.5 epoch. We used a digital map of the ∆Bа induction module anomalies and B0, the Earth’s normal magnetic field. To calculate the components of the ∆Bа (the anomalous magnetic field), a 3D magnetic model of the territory of Ukraine was developed. It reflects regional and large local sources of the Earth’s crust. The values of the Earth’s normal magnetic field’s components, B0x (northern), B0y (eastern), and B0z (vertical), were calculated using the analytical model of the Earth’s main magnetic field (IGRF-14). The power Bx, By, and Bz components of the geomagnetic field vector were obtained as the sum of their anomalous and normal values at points along a 10×10 km grid, and the angular, declination D and inclination I, were calculated.
