In two different experiments, a magnet is moved close to an iron bar that has not been magnetised. As a result, the bar becomes magnetised. Which magnetic pole is induced 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
