Fig. shows a magnetic compass. What will happen to the position of its needle if you bring a bar magnet near it? Draw a diagram to show the effect of the needle on bringing the bar magnet near it. Also, draw the diagram to show the effect when the other end of the bar magnet is brought near it.
If we bring a bar magnet near a magnetic compass N, its needle will get deflected. When we bring North pole of a bar magnet near the magnetic compass, its needle will be deflected away from the magnet as shown in the first figure.
However, when we bring South pole of bar magnet near the magnetic compass, the needle will be deflected towards the magnet as shown in the second figure.
