The diagram above shows a magnet X with its south pole moved along a soft – iron bar PQ in the direction shown. After some time, the poles at P and Q respectively are
- North - North
-
North - South
- South - North
- South - South
The correct answer is: B
Explanation
When a magnet is moved near a ferromagnetic material like soft iron, it induces magnetism in the material. The end closer to the magnet becomes the opposite pole.
In this scenario, the south pole of the magnet X approaches point P. Point P becomes a north pole to repel the south pole, while the opposite end (Q) becomes a south pole.
