Theres no ground zero for magnetic field. Earths mass, the molten, spinning core is a dynamo, generating a field like a spinning motor. As long as the motor is on, the axis and spin rate never change, the earths magnetic field will continue, even if it 'flips'.
So what, the compass needles will point the wrong direction. Oh, and a zillion satellites will lose their way.
That could be interesting.
There's a wee bit more. The iron in the core is thought to be solid, and that there is an outer liquid core that carries ionized iron that moves around the outer core in a very slow process, and that is thought what causes the magnetic field, which then is variable, and the outer core is probably asymmetrical in its motion.

Ummm...I'm wondering how much truth there is in that solid core theory...
It seems to me that the core would contain the highest heat and pressure...if we have liquid iron that spews from the earth's mantle to the crust...wouldn't the iron at the center be liquid as well...?
The core is under considerably more pressure...if you compress liquid iron while increasing heat...wouldn't you end up with more dense liquid iron and not a solid...Per Se...?
With increased pressure in all directions inward...the viscosity would no doubt increase in conjunction with the density...
Still...I would think you would end up with a "rest liquid"...rather than an amorphous solid...an increased viscosity liquid in a rest state due to the increased density and pressure...

Being a magnetic field, that means every point in space has a direction and a strength. If the magnetic field flips then the strength in some places will reduce to zero then increase again but with a reversed direction. At the surface of the Earth, local magnetic fields take over, forming loops and arches much like solar flares do on the Sun.
Apparently Earth already has two North Poles and two South Poles, so they will probably fight it out:

To add to that, the densest heavy metals would go to the center, forming 'valence shells' if that makes sense, spinning at different rates due to their density, that would induce electro magnetic fields that surround the planet...(?)

Absolutely..
I’m not real knowledgeable o. The subject, but know waves can cancel each other out.
What if all those fields are negating any fields with the opposite frequencies.
Maybe all those waves that get negated add up...

When you say the core is solid, solid what? Heaviest metals will find center, all will be under such pressure they will be molten. Different densities will spin at different rates creating the magneto effect, that generates the Field.
Of course nobody has actually seen this, just going on what I know from smelting.
