nickel
There are many different compositions of meteorites. The meteorites that are thought to be analogous in composition to the Earth's core are made of iron.
The Earth's core is thought to be predominantly iron (85 %) with some (4-5%) nickel and the remainder oxygen, silicon, hydrogen and carbon and a number of siderophile (iron liking) elements that descended to the core with iron during planetary differentiation.
Convection currents in the Earth's molten core are thought to be responsible for causing Earth's magnetic field.
The composition of the Earth's core (iron and nickel) is implied by the elemental composition of meteorites, which contain substantial iron. The gravitational field of Earth also suggests an average density that is consistent with a large iron content. Additionally, the Earth's magnetic field is assumed to depend on a large core of ferromagnetic elements.
The material is hotter and denser.

Yes, this is because many meteorites derive from bodies that formed and differentiated (like the Earth) early on in the formation of the solar system but were then shattered by impacts, exposing their core material. This material is thought to be an analogue for the composition of Earth's interior.

the outer core
The most common element in the Earth's crust is actually oxygen. Silicon, aluminium, and magnesium are also very common. The Earth's core is thought to be mainly nickel and iron.
