How do some animals use magnetic fields to migrate?

The Earth is a giant magnet but we don’t usually think about it since magnetic fields are invisible. While we can’t see magnetic fields the way we can see the sun and stars, some animals have specialized body parts that allow them to detect these fields and then use them to migrate. Check out this video that describes a few of the neat features some animals have. Whether it be small amounts of ferromagnetic metals in their cells, to specialized molecules in their eyes, we still have so much to learn about animals!
