Answer 1

let us take one bar in hand, now take this bar towards other two bars, if there is no attraction or repulsion  of the bar in the hand with the other two bars, the bar in the hand is no magnetic material .

Now take second bar in the hand now move this bar towards the third bar if third bar follows the motion of the second ie magnetic materials gets effected  by the magnetic field it means the bar in the  hand the magnet  and the third is the magnetic material therefore we can identify the three material bars
