In two separate experiments, a magnet is brought near to an unmagnetised iron bar. This causes the bar to become magnetised.
Which magnetic pole is induced at X and at Y?

pole induced at X:N / pole induced at Y:N
2 )
pole induced at X:N / pole induced at Y:S
3 )
pole induced at X:S / pole induced at Y:N
4 )
pole induced at X:S / pole induced at Y:S
