Explanation:
The phenomena which help form Earth’s magnetic field includes;
I. Rotation of Earth on its axis.
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.
II. Motion of metal in Earth's outer core.
When planet earth spins on its own axis, the iron found within a liquid outer core moves around which typically gives rise to powerful electrical currents to be generated inside the liquid iron.
