What happens in earth's interior to produce a magnetic field describe the layer where the magnetic field is produced?

The rotation of Earth on its axis causes electric currents to form a magnetic field which extends around the plane

Explanation:

On Earth, flowing of liquid metal in the outer core of the planet generates electric currents.

the answer is b i think

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
