An artist is preparing two permanent rod magnets for a kinetic sculpture. One end of the first magnet is labelled P and one end of the second magnet is labelled Q. A reference magnet has its north pole labelled N.
The artist records these observations.
| Ends facing each other | Observation |
|---|---|
| N and P | The ends move apart |
| Unlabelled end of the first magnet and Q | The ends move together |
Which statement correctly identifies the labelled ends P and Q?
P is a north pole and Q is a north pole.
P is a south pole and Q is a north pole.
P is a north pole and Q is a south pole.
P is a south pole and Q is a south pole.
