Time-Evolution of the Earth's Magnetic Field During a Simulated Reversal
Shown is the radial magnetic field of our Earth-like dynamo (chemical convection at E = 3x10-4, Pm = 3, Ra = 35 times critical). Red colors positive, blue negative values. The animations cover the time interval from Fig. 8 of Kutzner and Christensen (2002) , see also Fig. 9 therein. Time t above the animations is given in magnetic diffusion time.
