How do magnets help in navigation

Magnets have been used in the form of magnetised needle or compass that guides navigators and explorers to find their way when they travel. Earth has two magnetic fields with two poles - North and South Pole. The magnetic compass contains a needle which swings in the direction of North-South due to Earths magnetic field. The compass thus is an important tool for navigation due to Earths magnetic field.
