Describe how earth's magnetic field is generated?

The Earth's magnetic field is believed to be generated by electric currents in the conductive material of its core, created by convection currents due to heat escaping from the core.

Convection current that originated form the earth core.

Explanation:

The earth magnetic properties are a produce of those of the core of the earth that are deep down. us happens due to the iron rich core generate the waves that occurs in the current form and this occurs due to the interaction of the inner and the outer core. The difference in the temperate, pressure and the componstion of the ouuter and the inner circle is reosocble for this convective cells and hence the wamng and coolg of these layer of core createa liquid flow that passes this electc curent ad that  is known as a geodynamo efect.
