The Earth's magnetic field is generated by the complex interplay of convective flows in its liquid outer core, a process commonly referred to as the geodynamo. The dynamics of this magnetic field are ...

For generations, scientists have known that Earth’s magnetic field is uneven. Some regions exhibit stronger magnetic fields, while others exhibit weaker ones. One of the most prominent weak regions, ...

The Earth's internal magnetic field varies on timescales of months to billions of years. The field is generated by convection in the liquid outer core, which in turn is influenced by the heat flowing ...

Washington, D.C.--Earth's magnetic field is generated by the motion of liquid iron in the planet's core. This "geodynamo" occasionally reverses its polarity--the magnetic north and south poles swap ...
