Paperback. Condition: New. Print on Demand. This book presents scholarly investigation into the relationship between the natural phenomena of geomagnetic dip and variation and the internal structure and properties of the Earth. Conducted over several years, this study involved fitting specially adapted dipping needles to seafaring vessels and relying on detailed data provided by volunteer sea captains. The results comprehensively support the theory of a single spherical lodestone positioned at the Earth's core, with predictable variations in the dip and variation at different latitudes, providing valuable new insights into the planet's magnetic properties and internal composition. The findings hold significant implications for the development of improved methods for terrestrial navigation.
