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.
Energy is released when protons flip in a magnetic field. :)))))
Other planets
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.
Yes. In historical times , clay pots have shown that the earth's magnetic field has reversed.
Current flows inside he Earth.

It is Earths' "Magnetosphere".
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
the earths magnetic signature is a negative polarity signature
earths magnetic field is generated by the circulation of liquid metal.
It is Earths' "Magnetosphere".
magnetosphere
No. Earth's magnetic field does not affect its axis of rotation.
