The metal rod is non-ferrous, or the metal rod has an opposing electrical charge.

Any non-ferrous metal (aluminum, copper, magnesium, etc.) would not be attracted.
If the magnet was a bar magnetic then the metal rod could have been magnetized and the the same pole used for the experiment. (This would be repelled, not attracted). This would not work with a horseshoe magnet since the field has both a N and a S pole facing the rod.
There is a third condition: The distance between the magnet and the rod was too great or contained a barrier to the magnetic field (such as 4 inches of steel).

1. Magnet has no more magnetic field, or maybe
2. The metal rod can be also a magnet, but facing the opposite pole with the magnet

maybe:-
1) the magnet is defunct. (like the magnet has been drop to the floor or etc)
OR
2) the metal rod and the magnet have the same electrical charge.

Maybe its one of those metals that dont become magnetic

Some metals are not magnetic, like aluminium, magnesium, etc.
