It protects us from the magnetic/electrical radiation that mainly comes from the sun. High radiation periods coincide with solar storms, et al.
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
Yes.
because it has the hydro electric power to control the earths magnetic field
The earth's magnetic field is important in that it prevents the sun's solar radiation from killing life on earth by wiping out the earth's atmosphere and deflecting dangerous radiation.
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
Magnetic Reversal
It is Earths' "Magnetosphere".
It is made by the movement of the earths core and magma field
The movements in the liquid inner core.
This is known as magnetic reversal when earth's magnetic poles change places.
The movements in the liquid inner core.
