What happens to the magnetic field structure globally during a reversal process?

Answer

The main dipole component significantly weakens, becoming a complex, non-dipolar pattern.

During the transition, the simple dipole structure breaks down, the field weakens dramatically (perhaps to 10% strength), and a complex, multi-pole configuration emerges globally.
