Two bars are each marked at one end with an X or a Y, as shown. End X of bar 1 is brought close to the N pole and then to the S pole of a magnet. End Y of bar 2 is brought close to the N pole and then to the S pole of the magnet. The table shows what happens. | | end X of bar 1 | end Y of bar 2 | |---|---|---| | N pole of magnet | attracted | attracted | | S pole of magnet | attracted | repelled | Which materials are bar 1 and bar 2 made from?

1. Abar 1: copper, bar 2: iron
2. Bbar 1: iron, bar 2: steel
3. Cbar 1: steel, bar 2: copper
4. Dbar 1: steel, bar 2: iron
