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.

What is released when protons flip in a magnetic field?
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.
What forms when earths magnetic field changes direction?
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 what is released?
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.
When is earth's magnetic field going to flip?
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.
Where is the Earths magnetic field at its strongest?
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.
What is the earths magnetic flip?

Is earths core a source of earths magnetic field?
Yes.
How are the Earths magnetic field made?
It is made by the movement of the earths core and magma field
What is released when protons flip in a magnetic field?

Earth's magnetic field results from the spinning of the?
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.
Why do scientists believe that the inner core is the source of earths magnetic field?
because it has the hydro electric power to control the earths magnetic field
What is earths magnetic field called?
It is Earths' "Magnetosphere".
Where does the earth's magnetic field get its power from?
earths magnetic field is generated by the circulation of liquid metal.
