Explain work earths magnetic field originates from and how it is produced. Also list two benefits the magnetic field provides

Question

The force feild surronding Earth is called the magnetic Feild.

Answer 1

 Earth core is made of molten  iron at high temperature. Due to difference in temperatures and pressures within the core, the iron flows  which produces  electric currents which in turn produce the magnetic field for the earth.

Two benefits of the field are:

1-protection from harmful radiation. Charged particles are forced to go around the earth because of the magnetic belt.

2-protection from solar wind.
