a) Evolution of the magnetic dipole components from the model data (with time-independent amplitude of poloidal field injections, which are of arbitrary sign). b) Evolution of azimuth (see comments in the text).If the half-period (0.176) of the oscillations in panel a) is identified with the 11 yr sunspot cycle, then the time unit is about 62.5 yr.
