3 **similar **iron rods **does not mean they are exactly the same.**

iron rods will be attracted to a magnet on either side

only magnetic iron rods has polarity of N and S

So AB is an iron rod but CD and EF are both magnets

Hence, regardless of end A or end B, they will both be attracted to a magnet on either end.

Since D repel E, they are magnets and it means that say, C is N and D is S, then E is S and F is N

So in conclusion, answer is (2)

end A, attract with end F because EF is a magnet and A is one end of an iron rod

end B, attract with end F because EF is a magnet and B is one end of an iron rod

end C, repel because C is N and F is N

End D, attract because D is S and F is N

Great answer, but I’m not sure if it is a fair question.

If an unmagnetised magnet rod sticks to a magnet, doesn’t it become magnetized with a north-south pole too? The question did not say the rods are separated before the test is conducted on the rods separately.

I think that should be stated.

Thank you so much sushi88.. god bless you. ;))
