Question

What are the probable causes of the earth’s magnetism?

Answer 1

In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal. The electric current, in turn, creates its own magnetic field—one that is stronger than the field that created it in the first place.

Answer 2

Answer:

It is believed that the source of earth magnetic field is the molten charged fluid which gives rise to circular electric currents inside the core of the earth
