THE EARTH'S molten iron core creates a MAGNETIC FIELD!

 

MAGNETOSPHERE

The Earth is sort of a great big magnet , with poles at the top and bottom near to the actual geographic poles. The magnetic field it creates extends thousands of kilometers out from the surface of the Earth - forming a region called the "MAGNETOSPHERE." This Magnetic Field is generated by the molten iron core of  the earth , wherein heat creates convection motions of a conducting materials to generate electric currents.

Be grateful for the magnetosphere Without it particles from the Sun's  solar wind would hit the Earth directly , exposing the surface of the planet to significant amounts of radiation .Instead , the magnetosphere channels the solar wind around.
