Question

Studies have shown that a certain type bacteria that live in swamps have a magnetized chain of magnetite as part of their internal structure. The magnetized chain acts like a compass to help the bacteria align itself with the Earth's magnetic field. It is found that in the Northern Hemisphere this bacteria has internal magnetite chains that are opposite in polarity to those of similar bacteria in the Southern Hemisphere. Why? Explain.

Could you please give detailed explanation. Thank you!
