Yes- in the distant geologic past it has flipped several times, as shown by the orientation of metallic minerals in rock that formed at those times, especially that of the seafloor.
The phenomenon you're referring to is known as geomagnetic reversal or magnetic pole reversal. This occurs when the Earth's magnetic field flips its polarity, causing the magnetic north and south poles to switch positions.
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.
When Earth's magnetic field changes direction, it results in a phenomenon known as geomagnetic reversal or magnetic flip. This process involves the magnetic north and south poles switching positions. These reversals have occurred throughout Earth's history and have been recorded in the rock record.
Earth's magnetic field is strongest at the magnetic North Pole and the magnetic South Pole.
