• Magnets show a wide of properties which were used in ancient times for many purposes.
• One among such property was to find directions using bar magnets.
• The property associated with bar magnet is when it is suspended freely in air using a thread it always points to the North-South direction.
• So here when the bar magnet is suspended in air freely the north pole of the magnet points to the north direction of earth and similarly the south pole of the bar magnet points to the south pole of the earth.
