In two different experiments, a magnet is moved close to an unmagnetised iron bar. As a result, the bar becomes magnetised. Which magnetic pole is produced at X and at Y?
- Apole induced at X: N, pole induced at Y: N
- Bpole induced at X: N, pole induced at Y: S
- Cpole induced at X: S, pole induced at Y: N
- Dpole induced at X: S, pole induced at Y: S
