Answer the following questions:

The charged currents in the outer conducting regions of the earth’s core are thought to be responsible for earth’s magnetism. What might be the ‘battery’ (i.e., the source of energy) to sustain these currents?

The charged currents here refer to the convection currents in the core of earth, which is responsible for earth’s magnetic nature. This current is sustained partly by the Coriolis force due to rotation of earth, which rotates the molten core.
