Why does the Earth behave as a huge magnet
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet. The magnetic field is extremely important to sustaining life on Earth.
Answer:
The Earth behaves like a magnet because the Earth is a magnet. It is not a permanent magnet, but an electromagnet.
We now understand why. Deep in the Earth, molten metal (mostly iron) flows due to heat which causes convection. (The heat appears to be generated by iron condensing at the solid core.) This flow tends to organize itself into patterns, just like the patterns you’ll see in oil if you heat it in a frying pan. Such patterns in a flowing conductor tend to create magnetism. The same idea is used in the “dynamo”, a device that creates both electric current and magnetism from moving conductors. Commercial dynamos are the source of essentially all of our wall-outlet electricity.
