The planet (or moon) must have a magnetic field. This means the body must have an iron core. A star can have a magnetosphere without an iron core because it is composed of plasma.
Iron is fused within a star's core. When sufficient iron has accumulated and it begins to fuse, the energy of that fusion is too great and the star explodes creating all the heavier elements.up ya bum
You have already answered your own question. The: "Iron Core" is the... Core. And the... Core is located in the center of the Earth.
Outer core - predominately liquid iron and nickel. Inner core - predominately solid iron and nickel.
Supernovas, other than Type Ia are initiated when too much iron builds up in a star's core. Fusing iron and heavier elements absorbs energy rather than releasing it. Once the core reaches the point that it no longer produces energy it collapses, causing the star around it to explode.
in its core there is molten iron
IRON
from silicon to iron, about a day.
Because it basically has to do with three variables. The star's SIZE, its MASS and TEMPETURE.
The star "burns out" because iron cannot be fused. What happens then depends on the star's remaining mass:low - white dwarfmed. - neutron starhigh - black hole

If you mean the inner core of the star, that will initially be the same as the remainder of the star - mainly hydrogen, and a small amount of helium. As the star burns up the hydrogen, the amount of helium will increase. Once there is not much hydrogen left, the star will get hotter, and burn helium, converting it into heavier elements.
Unlike lighter elements, fusing iron consumes more energy than it produces. This does not, however, cause a star to cool. Once a star gets to the point of fusing iron, the core stops producing energy and without the pressure from the heat it produces, the core collapses while the rest of the star is blasted away in an explosion.
what is iron core inductors
New elements - helium always, heavier elements often (up to iron) and heavier than that if the star explodes.
