Answer Details

When a magnet is moved along a soft-iron bar, the bar becomes temporarily magnetized. In this case, the south pole of the magnet X is moved towards point P of the bar PQ. As a result, the end of the bar near P becomes a north pole while the end near Q becomes a south pole. Therefore, the poles at P and Q respectively are North and South. So, the answer is "North - South".
