Ram has one bar in each hand of his. It is known to him that one of them is a magnet and the other is a magnetic material but not which bar is the magnet or which one is the magnetic material. He brings together the ends of both bars. He feels that there is an attractive force between them. Now he repeats the experiment, but this time, he brings together the end of the bar in his left hand and the centre of the bar in his right hand. He experiences an attractive force but one which is weaker than the earlier force. What could be the correct answer?

The correct option is A Bar B is magnet, Bar A is magnetic material
The poles have the higher concentration of field lines, so the magnetic force of attraction is more in that region. Hence, when we bring a magnetic object near the pole of a magnet it will get attracted to it with a greater force than when we bring it closer to the centre part which has less concentration of field lines.
