how the earth act as a magnet

WHEN EARTH IS ROTATING IT SELF THEN CHENTRIPETAL FORCE CREATED.THAT''S WAY THE EARTH ACTS AS A MAGNET

Hello student,

Earth has a molten liquid core containing iron. It is believed that as it moves or spins, it creates an electric current that causes a magnetic field around the Earth. The field is believed to be created by this dynamo action. The magnetic field makes the Earth act like a huge magnet so it attracts like one. That''s why it pulls the magnetized needle in a compass and makes it point in the general direction of the North Pole.
