This radio broadcast looks at the mysterious way in which certain animals can travel vast distances around the planet, using the magnetic field of Earth to guide them. Migrating birds, fish, sea turtles, honey bees and even bacteria have all been found to navigate using the magnetic field of Earth, sometimes over quite enormous distances and reaching targets of only a few degrees in width. There is discussion about where magnetic receptors may be within animals and that particular cells in migratory creatures contain magnetite, a substance which humans used many hundreds of years ago to create the first compass. This radio broadcast discusses animal magnetism with researchers who have been working with sea turtles, to discover just how the ...
