WAEC Physics 2016 Paper

Concept:The end of a soft iron bar nearest a magnetising pole acquires the opposite polarity.Explanation:End $P$ is placed near the North pole of the magnet.So the induced polarity at $P$ is South.End $Q$ is placed near the South pole of the magnet.So the induced polarity at $Q$ is North.Therefore, the polarities at $P$ and $Q$ respectively are South and North.Answer:A. S and N
