The south pole of a bar magnet is placed in turn next to each end of a metal rod A. Both ends of rod A are attracted towards the south pole of the magnet.
The experiment is repeated with the same bar magnet and a different rod B. This time, one end of rod B is repelled by the south pole, whilst the other end of rod B is attracted towards it.
From which materials could the rods A and B be made?
Rod A: copper; Rod B: steel
Rod A: soft iron; Rod B: steel
Rod A: steel; Rod B: soft iron
