10. Harun has three unidentified rods X, Y and Z. The rods can be either magnet, copper or iron. To confirm
their identity, he placed a bar magnet near one end of the rods X, Y and Z shown in figure below.

B. Iron Copper Magnet
C. Iron Magnet Copper
D. Magnet Iron Copper

11. Study figure below.
(SPE/2013/Q46b)

Metal rod YZ is brought near a magnet. End Y is attracted when placed near to the N-pole of a magnet. Page82
End Y is also attracted when placed near to the S-pole of the magnet.

a) Using the words; move towards, move away or nothing happen, predict what will
happen when end Z is brought near to:
the N-pole of the magnet: _____________________________
the S-pole of the magnet: _____________________________

b) Explain your observation stated in part i).
________________________________________________________________________________
