Yes it can reverse from North to South
Ancient pottery shows movement of the earth's magnetic field. Firing the pottery fixes the ambient magnetic field in the fired pottery.
Yes.
It is made by the movement of the earths core and magma field
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.
because it has the hydro electric power to control the earths magnetic field
It is Earths' "Magnetosphere".
earths magnetic field is generated by the circulation of liquid metal.
It is Earths' "Magnetosphere".
= An effect of the magnetic field is "Van Allen radiation belt" =
The Earth's Magnetic field.
Earth's magnetic field is strongest at the magnetic North Pole and the magnetic South Pole.
The strength of Earth's magnetic field is strongest at the magnetic poles, which are not necessarily aligned with the geographic poles. The magnetic field is weakest at the magnetic equator.
