  The structure of geomagnetism is very complex, and there are still some
problems left in magnetohydrodynamics (MHD) simulations. Recently, the macro
spin model has been suggested. This is the idea that geomagnetism is described
by interaction with many local dynamo elements (macro-spins). This model can
reproduce some features of geomagnetism by solving equations of motion with
only one variable. In this paper, we study this model to make more general by
adding one variable. In this result, our model becomes possible for several
things that are not treated in the previous study, for example, migration of
the North (or South) Magnetic Pole, comparison with observed data of magnetic
field distributions expressed in two directions, etc. Moreover, as a result of
an application to the sun, we could reproduce periodic polarity reversals and
the power index of the power spectrum, etc. In addition, we investigate the
statistical properties of the pole migration.
