Iron's is well below the accepted temperature of the Earth's core. I also happen to go by the plasma theory. My view of it is that the Earth's inner core is plasma. The outer core is molten iron. The Earth's surface magnetic field is a product of crustal and aesthenosphere magnetics. The interplanetary magnetic field is a product of both the Sun and Earth (and other planets) all interacting...with Earth contributing more at close distances and the Sun more at further distances....while other planets also contribute small influences. The total planetary influences on the Sun is exhibited by what is known as the solar system's barycenter. The mainstream ascribes barycentric motions of the Sun to gravity while the electric universe adherents would ascribe it to electromagnetic forces which they have found to be responsible for the effect we call gravity. So the Sun traces out its own orbit around the barycenter. This movement also influences how the magnetic fields within the Sun behave. And it's cyclical. Mark Adler , Retired NASA JPL System Engineer and Project Manager: " The Sun, the Earth, Jupiter, etc. are all "orbiting" the center of gravity of our solar system, its barycenter, which defines an inertial frame of reference. Just as in your simpler example, the two equal-mass bodies are orbiting their center of mass — not each other. Since the mass of the Sun dominates our solar system, the barycenter tends to be inside or very close to the Sun.The "orbits" in this many-body system are not simple ellipses, so the motion of the Sun relative to the barycenter (drawn here as the motion of the barycenter relative to the Sun) looks like this:" quora.com So, as for the Earth's inner core. A plasma sphere, surrounded by the outer core. The boundary between inner and outer core would be a surface. Just as the Sun has a surface. On the Sun, plasma is converted to all the elements up to iron. It is most likely a fusion process achieved within the granules, as they are called, seen in close-up imagery of the Sun. skyandtelescope.com The heaviest element possible for fusion to create is iron. So, having the greatest mass of the elements produced on the Sun, it would also be likewise on the surface of Earth's inner core. Also, having the greatest mass it would migrate away from the core at a much slower rate than say, silica (Which is found all over the planet's surface) thus producing the outer core. Since the plasma sphere at Earth's center is extremely small and much less powerful than the Sun's, it does not have the energy to blow away its formed elements in a "solar wind" so the elements accrete into a solid mass...a planet. This also explains the spreading of mid-ocean rifts as more mass is added and the Earth actually, very, very slowly, grows in size. The plasma input (exhibited by the aurorae at the poles) to the core is achieved at the poles due to the magnetic field lines observed for the planet. Likewise with the Sun.
