In one word, why is the Earth a magnet?

The Earth acts like a giant magnet, with a North and South pole like a bar magnet. This magnetic field helps protect us from dangerous radiation from space. Earth's magnetic field also helps animals like birds and sea turtles navigate!
Earth as a Magnet

Magnetic field: An invisible force that surrounds the Earth and is created by the Earth's internal magnetic core. Magnetic North Pole: The point on Earth's surface where the planet's magnetic field points vertically downwards. Magnetism: A force of attraction or repulsion that acts between objects that have a magnetic field.

Earth acts like a magnet because it has a molten core of iron and nickel. This creates a magnetic field around the planet. The Earth's core is so hot that it is partly liquid. It is estimated to be around 4,400-5,400 degrees Celsius. The Earth's magnetic field protects us from solar winds, which are bursts of charged particles released from the sun.
