ABSTRACT: Using the domino dynamo model, we show how specific axisymmetric and
equatorial symmetric forms of the heat flux variations at the core-mantle
boundary change the frequency of the geomagnetic field reversals. In fact, we
are able to demonstrate the effect known from the modern 3D planetary dynamo
models using an ensemble of interacting spins, which obey equations of the
Langevin type with a random force. We also consider applications to the giant
planets and offer explanations of some specific episodes of the geomagnetic
field in the past.
