About 780 000 years ago was when the earth's magnetic field last flipped.
In summer 1960-61, a USARP party led by Franz van der Hoeven, left Scott Base, Antarctica to traverse Victoria Land, the territory lying to the west of the Ross Sea.
In the course of this traverse they found a series of gravity anomalies which inferred a strike of a group of bolides. This has more recently been confirmed by satellite measurement.
The date of this impact is coincident with the last geomagnetic reversal, but no cause-and-effect is yet shown. This area is close to the location of the South Magnetic Pole.
The magnetic field is believed to be caused by electrical currents in the magma, running approximately parallel to the equator. [Or the net sum of a parallel of such currents.]
Slight disturbances in these conductivity paths could easily move the route of the current, thus changing the position of the poles.
When protons flip in a magnetic field, they release radiofrequency energy. This phenomenon is the basis for magnetic resonance imaging (MRI), a technique used in medicine to create detailed images of the body's internal structures.
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.
When protons flip charge in a magnetic field, they release photons. This process is known as magnetic resonance and is the principle behind techniques such as magnetic resonance imaging (MRI) used in medical diagnosis.
No one really knows because it all doesn't flip at the same time. Some areas will start to flip and mix with the magnetic field, thus causing it to flip. This is scheduled to happen in the next millennium=1000 years.
The Earth's magnetic field is strongest at the North and South magnetic poles, which are not the same as the geographic North and South poles. The magnetic field strength varies at different locations on the Earth's surface.

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.
