The Earth is like a magnet because it has a magnetic field generated from the Earth's iron core and the spinning of the Earth.
Why is the Earth said to form a magnetic field?
The Earth has a magnetic field thanks to a dynamo effect. The moving liquid iron core creates electrical currents, while the Earth's rotation on its own axis causes these currents to generate a giant magnetic field.
Because of its core made of liquid metal, the Earth works like a huge magnet with positive and negative poles. The magnetic field is the "layer" of forces around the planet between these two poles.
