Yes, that will work. Over to you!
The other way is to hold one and bring its end towards the centre of the other. If the one you're holding is the magnet, it will attract the iron rod. However, if you're holding the iron rod, the magnet will not be attracted to it, as in the middle of the magnet there's no net magnetic field.
