Magnets are used in our daily life and many other devices due to their property. Here, some of those uses are given in detail.
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.

Magnets are used in compasses to show the north and south directions for navigation. Mountaineers and hikers use the compass for finding paths in unknown places.

Magnets, in general, are used to generate electricity in dynamos. The usage of magnets plays a vital role in small electric motors and some door locks.

Electromagnets are used in our day-to-day life. They are used in electric bells, loudspeakers, and microphones.
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.
