Description
Main part of the geomagnetic field is generated by dynamo process in the
Earth’s core.
This implies that the geomagnetic field and its secular variation have
potential to reveal
the dynamics of the Earth’s core. In this talk, I am going to introduce
recent progress
of the studies of Earth’s core using the geomagnetic field. It has been
suggested that
decadal variation of the geomagnetic field is compatible with stable
stratification at the
top of the core although the cause of the stratification is not very
certain yet.
