Now coming to your question, I would like to give it a try.
If both the bars are identical then let's assume that both of them are magnet. Now if they are magnet then they will definitely have south and north pole. Mark N and S on both the corners of the bar for your convenience. Now keep the bars horizontally aligned in one line. So the following combination will be there:-
NS SNNS NSSN NSSN SN
So now if both the bars are magnet then they will attract each other only in 2nd and 4th case( opposite poles attract each other) and they will repel each other in 1st and 3rd case. (Similar poles repel each other).
But if they don't show repulsion at all then one them is magnet and another one is iron.
And if they don't even show attraction also then none of them is magnet.
As per my knowledge, I think I have correctly answered it. Corrections and suggestions are welcomed.
