The liquid part of the Earth's core is primarily composed of the elements Nickel (Ni) and Iron (Fe). As the core and mantle exert gravitational forces, the temperature of the inner core, which is nearly pure iron, gradually decreases outward. This cooling process leads to the release of light sulphur at the boundary of the inner core.
On the other hand, convection occurs within the outer core, which is characterized by the bulk movement of molecules within fluids. The liquid metal in the outer core convects rapidly enough to effectively track the magnetic field of the Earth. This movement creates a stretching effect that wraps the newly generated magnetic field around the Earth's core, forming multiple loops. Consequently, this process results in the development of a significant dipolar magnetic field.
The purpose of Earth's magnetic field is to protect the surface of Earth from harmful cosmic radiation and solar winds. Furthermore, it also keeps Earth's atmosphere tied to the surface of the Earth. Without Earth's magnetic field, compasses and other forms of navigation would not be functional.

It is the build-up of the shift or strengthening of the earth's magnetic field that causes problems for humanity and all life on it
During the period of the temporal flip of the magnetic field, certain areas of the earth's magnetic field will be weakened for a few hundred years while causing sudden changes in wind currents...
A lot of animals have magnetoreception, which is the ability for an organism to
Migratory Birds
Fish or sea reptiles
Mammals
E.g (Dogs, Cats, Deer and ...)
Insects and Crustaceans
This is not an exhaustive list as many other animals also have magnetoreception
