The formation of geo dynamo on Earth, or the self-sustaining process responsible for maintaining a magnetic field as the covective motion of its liquid core is converted into magnetic energy. These model simulations helps us to investigate and better understand how magnetic poles are formed and transformed with time.

Volume rendering of radial magnetic field A simulation of the convection-driven flow of an electrically conductive fluid in a rotating spherical shell. The fluid motion generates a self-sustaining magnetic field. Such simulations are used to approximate conditions, which generate planetary and solar magnetic fields.		br-field.png	2015-07-25 16:04
