Two nickel bars are positioned near the N-pole of a bar magnet. The nickel bars are magnetised. Which row gives the pole induced at $P$, the pole induced at $Q$, and the nature of the magnetic force between $P$ and $Q$?
- Apole at $P$: N; pole at $Q$: S; force: attraction
- Bpole at $P$: N; pole at $Q$: S; force: repulsion
- Cpole at $P$: S; pole at $Q$: N; force: attraction
- Dpole at $P$: S; pole at $Q$: N; force: repulsion
