No more metal objects in the room

Take one rod and stroke the other with it at right angles. After awhile, test to see if they are both magnetised by first putting them end to end and seeing if the attract or push. If they attract then turn one around. If they still attract then only one of them is still magnetised. Sooo, repeat the stroking but this time with the other rod.
You will know which one was magnetic to start with because you will only be able to magnetise the non magnetic rod by stroking a magnetic rod along it length ways.
And you will know when they are both magnetic because when held together with the same poles facing each other they will repel each other.

Use two pieces of string... tie a piece to the center of each piece of steel. Allow the pieces to suspend and 'spin freely'. Once they stop spinning the one that points 'north/south' is the magnetized one. If they both stop at the same place, give each a piece a slight spin and allow them to stop again. Again.. the magnetized one will always point the same north/south. If you don't know which is north, it doesn't matter as one will always point to the same point in the room and the other will point randomly.
That's my suggestion.

Find a way to float them in a liquid and the magnetic one will align with the magnetic north pole, the other one will not.

Water and something light that floats (but will bear weight) such a polystyrene sheet, place the steel on the polystyrene that is flaoting on the water and the magnetised piece will align its poles

If you touch a silver coin or pin to each piece of steel, the coin or pin that stays attached when you move your hand will define which piece of steel is magnetized. A magnet will hold onto anything that is metal or stainless steel due to the powerfulness. Something that is not of magnet form will only release the item.

Put them in T shape then slight to the end to become upside down L.You will know the answer.Assuming that they are metal bar.

Everything is magnetic, not just ferrous metals. Try everything else in the room, running water might show the correct one.

You've got me. What if you put the telly on, would the magnetized steel cause any type of interference, sound or vision?

the magnetized one is magnetized cuz the molecules are all lined up and creating a magnetic domain, but the other one hasn't had the molecules lined up yet

hold one each to a tv, if the colour distorts thats the magnet
