Or are they made of non-ferromagnetic materials? subisnack
The main component of the Earth's field – which defines the magnetic poles – is a dipole generated by the convection of molten nickel-iron in the outer core the inner core is solid, so its role is secondary; remember that the Earth's core is well above the Curie temperature, so the iron is not ferromagnetic.
The phase here is between a heavy fermion and light fermions in an anti-ferromagnetic state.
Moreover, he proved that ferromagnetic substances exhibited a critical temperature transition, above which the substances lost their ferromagnetic behavior; this is now known as the Curie point.
It has ferromagnetic life forms reprocessing much of the grand structures built by man, and man dying out in a world where the sun is fading.
The exceptions are things like ferromagnetic aneurysm clips and bullets, which could move and cause injury.
Here is an illustration of the idea in the natural sciences; the black line is the theoretical calculation of ferromagnetic properties, and the colored lines are the observed behavior of metals under difference conditions.
One hands-on model is with a ferromagnetic material which has different domains of magnetization.
It is generic to a wide range of processes from Curie point on ferromagnetic behavior, superconductivity, superfluidity, Landau electron phases and so forth.
The first physics with this characteristic was advanced by Pierre Curie as a way to understand phase transitions between ferromagnetic and paramagnetic properties of metals with temperature variation.
