I cannot tell you exactly, but if you can find the Hysteresis curve of the Earth as a geological permeability constant you might be able to use that.
1st. You will need to find the Earth's ferro-magnetic density as a mineralogical distrubution constant of ferro magnetic materials. This is an evaluation of the approximate geological average of ferro-magnetic materials present in the Earth.
2nd. Since, it is impossible to be absolute, the factor will have to have a maximum ferro-magnetic distrubution average, and a minimum ferro-magnetic distrubution average.
3rd. Since, it is impossible to determin the effects of outside forms of radiation the only factors that you can base this on is known factors that can effect magnetization. This would be in MegaWatt Hours, because Power lines, transformers, and generators develop the highest intensity of continually changing magnetic fields. Solar influences that can be measured can be accumulated, but not so plainly forcasted, only calculated into a present standing rate of change attributed to the man made factors, which are predictable.
Now, this may seem to tear away from the subject, but is there any direct coincidence to the direction of the Earth's rotation, and the direction of the magnetic field? In this sense, Convection changes the energy level of the atoms of which the Earth's surface is composed making more space for electrons. When the Earth cools, the atoms are less exited, and stay more tightly packed, leaving less room for electrons. As a result of this motion of electrons is the Earth being magnetized, or De-magnetized? In electro magnetizim, I already know that the Earth is the Opposite of North, because the Magnetic compass's North is the equal of the Earth's South. Opposites attract, and in electro-magnetics the compass points South to North, and North to South. The direction of the windings, would depict the direction of current flow around the core material.
I figure that if a large body impacts the sun, a spinning cloud of gas could retain a magnetic field significant enough to throw the Earth off of it's axis Magnetically as it passed over. The actual flip of the Earth would take days.
