Magnets are used in our daily life and many other devices due to their property. Here, some of those uses are given in detail.
 
1. Navigation:
Magnets were used in the form of direction stone or leading stone in ancient times. Sailors, during their voyages, used these stones to find directions.

4. Transport:
The fast-moving Maglev train uses a powerful electromagnet to keep it floating above the rails. It is the world's fastest train travelling at a speed of about \(500\) \(km/h\).

Magnetic levitation train or Maglev train has no wheels and works on the property of magnetic repulsion. The strong magnetic forces exerted by computer-operated electromagnets make the train float above its tracks.
