The Earth's outer core surrounded by magnetic field lines during the modeled geomagnetic reversal

The sphere is painted according to values of the radial component of the magnetic field B on the CMB (Core-Mantle Boundary): reds are where B points out of the Earth's center, blues - inwards. The field lines are colored according to the direction of the magnetic field: orange color - outwards (the radial component of the field is opposite to the gravity), blue - inwards. (Video: J.
