why does earth behave as a huge magnet
Answers
Explanation:
magnetic field is mostly caused by electric currents in the liquid outer core, which is composed of conductive, molten iron. Loops of currents in the constantly moving, liquid iron create magnetic fields.
From afar, the Earth looks like a big magnet with a north and south pole like any other magnet
Answer:
Earth act as a huge magnet because of the magnetic field which is produced by the electric current with the liquid of the liquid outer core.
The earth which acts as a magnet is not a permanant magnet but it is a electromagnet.
This current which causes electric current with the electric field is generated by the molten metal generally iron by the flowing, this flowing of metal causes convection which is passes into the core of the earth, passes through the crust and enters space.
