Geomagnetic Field Shapes Earth's Inner Core Structure, Study Finds

Researchers from the Institute of Geochemistry of the Chinese Academy of Sciences have found that Earth's anisotropic inner core structure is driven by the dipole geomagnetic field. The alignment of the Fe-H lattice could be driven by an electric field, which explains the anisotropic seismic velocities in the inner core. The study provides a new perspective to understand the mysteries of the Earth's inner core and Earth's magnetic field.
