The ocean generates its own magnetic field, which peaks everty 12.5 hours along with the rising tides.
Sea currents create electric currents through a process called motional induction.
Spiny lobsters have an amazing navigational sense called magnetic position fixing.
Sockeye salmon are sensitive to Earth's magnetic pull. Scientists discovered that salmon use a trick called "geomagnetic imprinting" to find their way home.
Have you ever wondered why the magnetic fields change places?
