Imagine the Earth is like a giant bar magnet, with north and south poles, just like your fridge magnets. Inside the Earth, there's a hot liquid called molten iron in the outer core that moves around because of heat. This movement creates electric currents, which make a magnetic field, kind of like a giant invisible compass that helps animals like birds and turtles find their way around the world.
Examples
- Birds use Earth's magnetic field like a map when they fly on long journeys.
- The aurora borealis is caused by charged particles from the Sun interacting with Earth's magnetic field.
