I get conflicting information as some sites, give data about the liquid core, or the outside of the solid core. But I'm looking for the exact center. What is the pressure? What is the Temperature? I understand that convection in the liquid core gives the earth a magnetic field, and that further from the source (on the crust) the field is weak, but it is stronger closer to the source. At its source what is the strength of the earth's magnetic field? What is the strength of the electric charge produced by the liquid core? The core is iron & either sulfur or oxygen. I assume that these elements are combined with iron in molecules, and that any pure oxygen or sulfur would have been forced from the core because it was less dense. If this is correct what compounds of sulfur, oxygen, iron would be there? Would one compound be rust? Are these elements different allotropes than above crust because of the conditions? Do they have different behaviors?
