Earth's magnetic field. Cutaway artwork of the Earth illustrating its interior and the pattern of its magnetic field. The Earth has a solid centre (inner core,purple),which is surrounded by a liquid layer (the outer core,yellow) where molten iron circulates (red arrows). The convective motion of molten iron in the outer core,combined with the effect of Earth's rotation is what produces the dipole magnetic field (lines) | |
