Detailed explanation-1: -Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly solid mantle. The core is found about 2, 900 kilometers (1, 802 miles) below Earth’s surface, and has a radius of about 3, 485 kilometers (2, 165 miles).
Detailed explanation-2: -The inner most layer of the earth is called the “Core or Barysphere”. It is otherwise known as NIFE, because of the presence of Nickel and Ferrous (iron). This layer produces earth’s magnetic field.
Detailed explanation-3: -There is indeed gravitational pull at the Earth’s centre. But, as the pull is coming from all sides, there is naturally no ‘apparent’ pull from the place where you are and so it would ‘feel’ as if there were no gravity at all.
