Question

what happens when you did a bar magnet in a pile of pins ?why?​

Answer 1

Answer:

If a bar magnet is dipped in a pile of pins, these pins would stick all over the magnet provided if they are made up of iron. This pattern of sticking of pins to the magnet shows that these pins get attracted towards the two ends of a bar magnet showing that these ends are the poles of the bar magnet.
