A student records tests on three permanent magnets. X and Y are ends of different magnets. Z is an end of the third magnet.
| Test | Result |
|---|---|
| X with Y | Repulsion |
| Y with Z | Attraction |
The student now tests the end opposite X against the end opposite Z. Which prediction and reason are correct?
Attraction, because these two ends are unlike poles.
Repulsion, because these two ends are like poles.
Repulsion, because these two ends are unlike poles.
Attraction, because these two ends are like poles.
