Question

You are designing magnetic motors. A colleague1 insists that like magnetic poles attract— north poles attract north poles and south poles attract south poles. You feel the need to remove this idea from his head. You possess three unlabeled bar magnets (that is, you don’t know which ends are N or S). Surely that will be enough. . .

Answer 1

Me: So i have three bar magnet and i would like to to find their polarity using the knowledge of north and south direction do you care to join me?

colleague 1 : Ok sure

Me: So the first i would like you to do is to tie a magnet and allow it to suspend freely

colleague 1 : Yes i have done that

Me : If you look at it you can see that the magnet has aligned itself corresponding to the north and south pole of the magnet,so this means that the side of the bar magnet pointing towards the north is the north pole while the side of the bar magnet pointing towards the south is the south pole.Now that you have seen how to identify each pole i would like you to repeat this procedure to identify the pole for the remaining two bars

colleague 1 : Ok i have done it

Me: Now i would like you to hold the north pole of one the magnet in a fixed position

Me : Have you done it

colleague 1 : Yes what next

Me: Now take the south pole of any of the two other magnets and bring it close to the free end(South pole ) of the fixed bar magnet and tell me what you discovered

colleague 1 : Wow it repelled it,but am not full convinced yet

Me: Ok try the process again this time make the south pole the fixed end and the bring the north pole of any of the other two magnets close to the free end(North pole) fixed magnet

colleague 1 : Ok you win yes it still repels
