The Magnetic Field

How does the magnetosphere help animal behavior on Earth?

Earth’s magnetic field is also very important to animals on Earth that migrate or otherwise travel long distances. Some animals have impressive built-in magnetic sensors; biologists have shown that many migratory birds figure out where to fly by using Earth’s magnetic field to guide them. Humans, too, benefit from the magnetosphere by using magnetic compasses to figure out which way is north or south.
