In this
case, to see which one of the two bars is a magnet, pick up one,
(say, A) and lower one of its ends; first on one of the ends of the
other (say, B), and then on the middle of B If you notice that in
the middle of B, A experiences no force, then B is magnetised If
you do not notice any change from the end to the middle of B,
then A is magnetised 5
