A compass is usually a small box with a glass cover on it. A magnetised needle is pivoted inside the box, which can rotate freely. The compass also has a dial with directions marked on it.
The compass is kept at the place where we wish to know the directions. Its needle indicates the north-south direction when it comes to rest. The compass is then rotated until the north and south marked on the dial are at the two ends of the needle. To identify the north-pole of the magnetic needle, it is usually painted in a different colour.
• Take a rectangular piece of iron bar. • Take a bar magnet and keep in contact with one of its poles with one edge of the bar of iron. • Without lifting the bar magnet, move it along the length of the iron bar till you reach the other end. • Lift the magnet and bring the pole (the same pole you staRead more

• Take a bar magnet and keep in contact with one of its poles with one edge of the bar of iron.
• Without lifting the bar magnet, move it along the length of the iron bar till you reach the other end.
• Lift the magnet and bring the pole (the same pole you started with) to the same point of the iron bar from which you began
• Move the magnet again along the iron bar in the same direction as you did before. Repeat this process about 30-40 times.
• Bring few all pins near to the iron bar and check if it is converted to a magnet or not.
Hang up the magnet by a light thread so that it hangs freely. When it comes to rest, we notice that the magnet is lying in a North - South direction. https://www.tiwariacademy.com/ncert-solutions/class-6/science/chapter-13/
